Yay, here's the one shot I promised, it's late, rushed this again, sorry

Muichiro's pov

"Muichiro… I love you!" Tanjiro yelled out, making my heart sink. I would never have imagined that someone like Tanjiro would say such words to me.. but.. I didn't mind because.. "I love you, Tanjiro.."

His eyes widened in excitement as he grabbed my cheeks, about to pull me into a kiss but stopped himself "oh shit! Sorry.. sorry, that was a little quick"

I smiled and kissed his lips quickly "it wasn't.. don't worry" I said shyly and looked at the floor. He touched his lips and his smile grew wider. The embarrassment disappeared so quickly and he just lift me up and did a little spin with me in his arms.

"You don't even know how happy I am right now, Mui! This is the best day of my life!" He said excitedly and I giggled, wrapping his arms around his neck.

Everything in that moment seemed so perfect.. Nothing could ruin such a perfect start of a relationship, right?

…right?

…

Just a couple days later I started to get messages from an unknown number which was odd but.. once I opened the chat.. it just got so much worse.

"Hello"

"Answer me"

"I see that you are online"

"Answer me god dammit!!"

"I give you 20 fucking minutes to respond to me, if you don't, I will do something.. you your little lover, hm?"

My heart sank when they mentioned Tanjiro. "What do you want.." I responded and just a second later, they started typing again. My heart was racing, my thoughts weren't stopping "who was this person?! What do they want?!"

"I want to play a little game"

"A game..?" I thought and texted the same thing right after. I regretted answering, thinking that they were just joking and I got myself into something embarrassing..

"Yes, a game, I will give you a dare every day for the next month.. if you won't complete them, your little boyfriend will get hurt.. or worse.. killed"

The second they mentioned the word kill, I immediately closed the chat and blocked the whole account. Not wanting to talk with them anymore.

"They must have been joking.. I am not gonna believe such things.. how stupid" I thought to myself and hopped on a call with Tanjiro instead, hoping that would take my mind off of it.

…

It was.. quiet for a while. No more texts.. calls.. anything so I thought that it was just some stupid prank but then.. something horrible happened.

I sat in my room, scrolling on my phone, about to just go to bed when suddenly I got a text from another unknown number.

"So you blocked me huh.. you don't even know how big of a mistake you did"

I was about to block the account again but then I saw "[user] has send twelve messages"

I took a small look at the photos, my heart dropping. They were pictures of me and Tanjiro.. some just of me all alone.. or Tanjiro.

Then another photo popped up, showing my and Tanjiro's houses.

"Are you willing to do what I tell you now?"

My hands started to tremble violently as I quickly typed "who are you?! What do you want from me?!"

"I just simply want you to follow my rules.. if you do, no one will get hurt, understand?"

"Okay…" I said, at this point having a full blown breakdown. I was panicking, not knowing what to do, who even was this person.

"Tomorrow you'll get the first dare, if you refuse to complete it, there will be consequences"

…

I stared anxiously at my phone as the unknown person typed my first dare I was supposed to do. They said that.. the dates will get increasingly harder and harder with each passing day which.. worried me.

"Alright, how about we start slowly, hm? How about you record yourself sitting at the edge of a roof? How does that sound?"

"A-A roof?! But- what if I fall??!" I thought to myself but knew that I had to do it if I wanted to keep me and Tanjiro safe.

"You're apartment building is enough, go on the top, and walk on the edge"

They typed and I took a shaky breath, walking out of my apartment and up the stairs towards the rooftop. I opened the door to be immediately hit in the face with a cold breeze of air.

My hands began to shake as I walked towards the edge, putting my phone on the ground and setting it the way the camera was a full view of the edge.

I started the recording and moved towards the edge, walking on it with shaky unsteady steps. Suddenly my gaze went to the other side, making me look down which made me stumble and almost fall down. I quickly got off the edge, my whole body shaking violently in fear and panic.

"That must be enough, right?!" I thought to myself and stopped the recording, sending it to him quickly. I waited for the answer while shaking, breathing heavily, feeling like I am on the edge of a panic attack.

"I-I almost fell! Th-this could hav-have been my end!" I thought to myself, my breathing almost out of control.

"Very well, I'll take this, I'll leave you be for the rest of the day.. but be prepared for tomorrow"

…

It was another day, the same time, the same spot in my room and the same anxiety while staring at the message the person wrote, knowing it'll be much worse.

"Almost died yesterday, hm? How about we make this time.. more challenging? Way more. Let's ask first.. are you scared of blades? Pain? Blood maybe??"

My heart sank, typing slowly with my shaky hands "I guess.."

"Well, how about you go take a razor and cut yourself? How would that feel?"

My voice hitched when I saw that message, looking at my arms before going back to the chat, replying with "okay.."

I slowly stood up and went to the bathroom where I locked myself, opening the cabinet with my shaky hand and grabbing the sharp razor that caught my eye.

With a shaky movement, I grabbed onto the iron blade, rolling my sleeve up and placing it on my pale skin, closing my eyes and slicing quickly.

I felt a sting, a small sting and then warm liquid sliding down my arm. I opened my eyes to see a small cut leaking blood. At this point I was crying, I couldn't believe that I was doing this. I couldn't believe that I was hurting myself!

"How much do I need to do..?" I texted, waiting for his answer while looking at the cut I made, shaking violently in fear.

"Five will be enough for now"

They said and I sighed in relief, expecting it to be way more. I placed the razor on my arm again, taking a deep breath and making a few more cuts really quickly so I don't feel the pain as much.

With a shaky hand, I placed down the razor and grabbed a tissue, soaking it a little with some water and cleaning up the blood before taking a picture of it.

I sent the picture quickly and reached for a bandage, bandaging my cuts quickly and cleaning up the floor that dripped onto the floor.

"Mhmm, good job.. we'll text tomorrow again"

…

As days passed, the dates were getting more and more challenging, affecting my relationship with Tanjiro and eventually.. one dare completely broke me.

"Break up with Tanjiro"

"WHAT?! NO! I CAN'T DO THAT TO HIM!"

"It's either you break up with him.. or he's dead"

My eyes filled with tears, starting to sob hard, breathing hard and grabbing onto my hand in frustration. Tanjiro was always there for me, I didn't want to break up with him, I love him!

I opened a chat with Tanjiro, quickly typing.

"Tanjiro.. we need to break up"

Immediately when I sent it, he saw my message and not even a second after he began to call me. I picked up the call, immediately hearing Tanjiro yell "Mui, what do you mean?! Did I do something wrong?! A- Mui are you crying?? What's wrong?!"

He yelled out in both confusion and worry. I began to sob harder "I-I am so-sorry! I am sorry! I don't wa-want to b-but I need to!"

With that I ended the call, taking a screenshot of the conversation and sending it to the guy, sobbing hysterically into my pillow, seeing Tanjiro spamming me with messages.

"Things are getting more interesting now, huh? I love how obedient you are, Muichiro…"

…

Day 30… 30 days since this nightmare started and feels like it'll never end. It ruined me completely, made me fear everything, lose everything, lose Tanjiro… even myself..

"Now now, day 30, hm? How about we make this goal interesting..? How about you'd.. kill yourself?"

My heart dropped immediately "what?! No! I am not doing that! No! I'll do anything else but I won't kill myself!" I texted in panic.

"...is that your final choice?"

After a bit of thinking, I decided not to reply, I turned my sound off, laid down in my bed and closed my eyes. I just wanted to fall asleep and escape this nightmare.. and.. I did.. but.. in a way I wasn't expecting…

…

??'s pov

"Oh Muichiro, if only you listened to me" I said to myself and placed my finger in the puddle on his blood, drawing on a wall with it.

"This is what happens if you don't follow the rules of my game.."
