Your POV:

Miu dragged Keebo to her lab after telling him she wanted to take their relationship to the next level. This worried me because that could mean very inappropriate things.
I was thinking whether to follow them or not, but my verdict was to follow them, so I can make sure nothing bad happens.
I honestly felt like the scene I walked in on wasn't meant for me to see. This did make me nervous.
"Rantaro.... I'm going to see what those two are up to..." I told him.
"Are you sure that's a good idea?" Rantaro asked in response.
"It doesn't matter if it's good or bad. A murder could happen or something else..." I replied.
Rantaro sighed as a response to what I said earlier. He was really opposed to me checking on them. It's not like I'd allow myself to be seen.
"Fine, but I'm coming with you," Rantaro told me.
"Fair enough..." I laughed in response.
All we had to do to get to Miu's Lab was to go straight through the trail that lead to Tenko's Lab, go through the center area of the pavement, and cross over to the trail to Miu's Lab.
That's exactly what we did to get to her lab. Rantaro and I silently went up to the door that led inside. I was careful not to make a sound. I opened the door just a slight peek, so I could see what was going on.
I heard a strange sound come from the room. My eyes scanned around the room to find the source of the noise. Suddenly, my eyes were met with an unbelievable sight that would be shocking to mostly anyone.
Miu was on top of Keebo, her bust being pressed up against the poor innocent robot. She had a blush on her face and the position she was in made it look very inappropriate. Keebo has his eyes clamped shut, but there was a noticeable blush on his face.
I felt my hand go up to my nose to cover it, because I felt like I was going to have a nosebleed. I felt so bad for Keebo, having to deal with Miu on top of him.
"Man... You're really plugged up," Miu said to Keebo with a playful tone, "you're practically throbbing.....Throbbing with dust and debris, that is."
'What is she doing?' I thought as I kept my hand placed over my nose.
    "Mm-mm... This is no good. No good at all. You must feel so pent up..." Miu told Keebo in that soft playful tone.
    "I apologize... I've been neglecting my needs ever since I got here..." Keebo replied with that same blush on his face.
    "Relax... I'll get all of it out. Trust me, you'll feel much better afterward..." Miu replied.
    "Oh, um... Thank you?" Keebo said as more of a question.
    This was very weird to me... I had no idea what this scene was supposed to be. Perhaps it was maintenance... but that couldn't possibly be it... it seems more of something else....
    "Oh yeah, your chassis is firm... *Really* firm. Like, damn..." Miu giggled playfully, "your body is seriously incredible! I've...never seen one like this..."
    "C-Careful... B-Be gentle... That tickles..." Keebo muttered.
    The blush on my face got worse. This didn't seem like maintenance... my innocent eyes were suffering. Rantaro was watching too, but we couldn't say anything. This scene was almost too much for me to handle.
    "This is amazing... Whoever put you together defiantly knew what they were doing..." Miu said to Keebo in pure admiration, "ahhhh... I feel...all tingly..."
    "Y-You definitely know what you're doing, too. If you keep this up, I just might—" Keebo stuttered, as he let out a very innocent, yet inappropriate sounding scream.
    As Keebo let out that scream, a large amount of bubblegum pink blood gushed out of my nose. I fell backwards as this was happening. I really couldn't take it anymore...
    As I started to fall onto the ground, it was as if it were in slow motion. The blood left a trail in front of me because I was moving backwards as it gushed out. Anime character nosebleeds seemed to apply with me...
    I was a dizzy mess on the ground because of the blood I just lost. That was maintenance.... but it was like I was almost watching hentai. I tend to stay away from that kind of stuff, but with Miu around, something like this was bound to happen eventually.

Rantaro's POV:

While watching the bizarre through the door, I should've paid more attention to (y/n). I did notice her covering her nose, but once Keebo let out some sort of moan-like scream, she fell backwards, blood spewing from her nose.
This worried me significantly, so I closed the door as fast as I could without making a sound. I went up to (y/n) after this and picked her up. She seemed too dizzy to even stand. She's *definitely* the Ultimate Otaku. She has anime nosebleeds surprisingly.
I knew I needed to find some equipment. Tissues. That's what she needed. I looked through my Monopad compartment to see if I had a box. I purchased some trinkets at the store with my Monocoins, but I didn't remember if I got tissue.
Looking in there, I had one box which was great. One box is plenty, or at least it should be.
I took (y/n) to the pavilion to be able to treat her without much trouble. When I got there, I rolled up tissue to put in her nose. I also wiped the blood off of her face. Somehow the blood didn't really get on her clothes. Just a few spots. She seemed to be more aware oh what was going on. This could my chance to give her a piece of my mind.

Your POV;

I groggily looked around. I was basically carried to the pavilion to have someone treat me for a nosebleed. I was embarrassed about it as well. There was a blush on my face from embarrassment.
"(y/n), I told you it was a bad idea to follow them..." Rantaro told me, "you caused yourself to have a very bad nosebleed..."
"In my defense, I had no idea my nosebleeds would be this bad..." I replied in a dizzy tone.
"How could you not know that?" Rantaro asked me in response.
I seemed to stay silent for a moment. I was still dizzy, and I had to think about why I didn't know.
"I'm basically innocent. I haven't had any close relationships that cause the birds or the bees. And I never even had a phone, so I can't watch inappropriate things," I finally explained.
"So it was a quote-on-quote, anime nosebleed?" Rantaro asked.
"Basically..." I replied nervously.
Rantaro sat me up so I could look at him. His eyes held concern for me. They were so soft and gentle... I could melt in them...
"You really do need to be more careful," Rantaro told me, "if you keep losing that much blood, you can die..."
"I know to be more careful... now that I know this is the case, I have to be..." I replied.
"Though, I have to admit. You were adorable while being a dizzy little mess," Rantaro told me with a small smirk.
This caused me to blush madly, instinctively putting my hand over my nose. He was messing with me, wasn't he.
"I-Is that supposed to be an insult or a compliment?" I stuttered.
"Obviously a compliment," Rantaro replied.
Was he trying to give me another nosebleed? I was trying to take deep breaths to calm down. I couldn't have another one... I've already lost enough blood today.
    Rantaro just chuckled slightly in response to my reaction. He seemed very amused by this.
    "I'm sorry," Rantaro told me, "I was just messing with you."
    "Why am I not surprised?" I asked with a slight blush, "you even screwed with me multiple times on the day we met..."
    "You're fun to tease," Rantaro said in response, "your reactions are adorable."
    I blushed again when he said that. Why did he call me adorable?
    "I told you I'm not pretty, cute, or adorable..." I told Rantaro with a pout.
    "Just sayin' you can't tell me what I can and cannot think," Rantaro replied.
"You try telling me what I can and can't say or think," I replied, "you're being a hypocrite right now."
"That may be true, but I have good intentions behind it," Rantaro replied, "I want to see you genuinely happy. I want you to see yourself the way I see you, the way the others see you. You can't see yourself the way others do if you keep acting like you are nothing. You aren't nothing. You have already done so much for the people around you. Please fight this for the people who care. The people in your past that made you feel this way don't matter anymore. Focus on now. Not the past..."
I was honestly shocked that Rantaro would say such a thing. Sure he was flirty at times, but he actually cared about me. He just wanted me to view myself better. That's why I was training with Kaito. With what I have now, I have helped people. Kaede would've died... Rantaro died, but I saved him. Kirumi murdered, but I gave her a second chance. I needed to start liking myself even though I didn't see myself the way he did. Maybe he'd like me better if I were more positive.
    "Alright..." I replied.
    "Good. Now, should we go back to the third floor to discover the area you unlocked?" Rantaro asked.
    "Sure," I replied.
    Rantaro and I made our way back inside. We traveled the first and second floor, before getting to the third floor.
    Once we got up there, I noticed Kaede and Shuichi were there. So we're Gonta, Kokichi and Tsumugi.
    "Where were you two?" Kaede asked, "did you guys unlock this secret passage?"
    "Yeah we did... I got cut from unlocking the secret passage," I explained, "we also used the scroll as well. Tenko's Lab was unlocked."
    "So are we going to go in there and see what we unlocked?" Tsumugi asked.
    "Nee-heehee, what do you think?" Kokichi asked.
    "Quit being rude Kokichi..." I muttered, "let's just go."
    We went into the passageway. It was more eerie than the third floor. We came upon a door that looked cybernetic. On top of the doorframe, it read "Computer Lab".
    "So this is a computer lab, huh?" Rantaro asked.
    "I guess so..." Kaede replied, "let's go in!"
    Once we opened the door and entered the lab, I saw a giant machine with what looked like to be smaller computers around it. I had no idea what this machine was.
    The Monokubs soon popped up, congratulating us on completing the puzzle. In reality, the only reason why I completed it was because of Monokuma.
    The Monokubs told us a little bit about the computer lab. The huge computer could create a virtual world. I  didn't think that'd be possible, but apparently it is.
    According to Monophanie, Monotaro said too much. Monodam was asking why she didn't help her. It was like he was obsessed with everyone getting along. You can't just force that onto others.
    Monokid was just obnoxiously yelling before they all disappeared with their stupid outro.
    I looked around the room since I already knew about the computer a little bit. I noticed a red and golden chest in the corner of the room.
    I hesitantly walked up to the chest and opened it. I pulled out a flashback light. I found the second one. After opening the chest, I heard quick footsteps getting louder and louder, signifying that they were getting closer.
    "Oh! You found the Flashback Light!" Kokichi exclaimed, ben f the source of running, "wooow! You're pretty dependable, despite that depressed face of yours! I respect that."
    "What's that supposed to mean?" I asked with a slight glare on my face.
    "Hey, whoa-whoa! I was kidding about the depressed part!" Kokichi exclaimed with a nervous smile, "a-anyway, I'll get the others. You just bring that to the dining hall, my beloved (y/n)."
    "Fine..." I muttered.
    "Welp, off I go! See yaaaaaaa!" Kokichi exclaimed before racing off.
    I let out a sigh from exhaustion. This was tiring and maybe it was because of losing blood.
    "I really don't get that guy..." Rantaro sighed, "it's almost as if he's obsessed with you... and I don't like it.."
