This will take place during Danganronpa 3: Despair Arc.

You

"Yeah, I know right? They're so demanding in this school."

Hajime

"Heh, I can agree with that."

Since you met each other in the reserve course, you and Hajime have been friends.

You

"Hey, Hajime, if you had an Ultimate Talent, what do you think it would be?..."

Hajime

"I would be... I'd be... Wow, I'm actually unsure of this. What about you?"

You

"Wait, wait, you seriously don't know?"

Hajime

"Heh, yup. I've got no idea what I'd be."

You

"Oh- Wow... Let's see... How about the Ultimate... Ooh, I know! The Ultimate Idiot!"

Hajime

"The Ultimate- Huh?! Where'd you get idiot from?!"

You

"Uh- Well, cause you act like one, duh?!"

Hajime

"Do I really? Explain to me how I act like an idiot."

You

"You once asked me how many sides an octagon had. Now, you can't really tell me that's not idiotic, right?"

Hajime

"W-Well-"

You

"Oh, oh! And let's not forget the time when you straight-up tried to punch some buff guy in his stomach when you knew damn well that you would lose the fight!"

Hajime

"H-Hey! He was-"

You

"And there's-"

Hajime

"Okay, okay! That's enough! N-Now, back to what I was trying to say, what would your Ultimate Talent be?"

You

"Hm... I'm thinking of... Hey, why don't you guess my talent?"

Hajime

"Huh?"

You

"Come on, you heard me! Guess the Ultimate Talent I'm thinking of right now.

Hajime put his hand on his chin.

Hajime

"The Ultimate... [Ultimate Talent]"

You

"Hm... That... That's actually not bad! I do {Ultimate Talent] a lot, so I guess it really fits in!"

Hajime

"Be thankful that I gave you the result you wanted... Did I guess it right?"

You

"Hmph... Yeah, you did."

Hajime

"Ha! Now, I can be the Ultimate Guesser!"

You

"That's a stupid Ultimate, Hajime!"

You got a letter from Hope's Peak Academy asking you to join Class 77-B a few months later.

You

"Hajime!"

You caught up to him, and once you did, you caught your breath.

You

"I did it! Look!"

You showed him the letter. After he read it, he awkwardly smiled.

Hajime

"W-Wow... You did do it. Good job..."

You

"I know right! I never thought that I would actually be given an Ultimate Talent!"

Hajime

"Hehe..."

You

"Hajime, are you alright?"

Hajime

"Hm?... Yeah, why?..."

You

"Are you upset that I have an Ultimate?"

He sighed.

Hajime

"Will you visit me sometime?..."

You were taken aback. You expected him to be disappointed since he didn't receive an Ultimate, and you got one. But the truth is that he was disappointed that you would no longer be in his class.

You

"Are you stupid? Well, there's no need to answer that question, but of course, I'll visit you! Nothing can break our friendship!"

You and Hajime spent the entire day together on your last day in the reserve course.

Hajime returned home after a big day with you, quite sad too.

Ms. Yukizome

"I'd like you all to welcome to our class, Y/N L/N, The Ultimate [Ultimate Talent]!"

It was a lot of pleasure staying with Class 77-B. You all travelled to so many places as a class that... Hajime began to realize that you had failed to appear at the fountain where you had both agreed to meet. You had a couple of encounters at the fountain before abandoning it.

Hajime

"Where are they?... Should I just contact them?"

He dialled your phone and waited for you to answer, but all he got was a message from your voicemail.

Hajime returned home with a concerned expression on his face. He was scrolling around social media when he came across photos of you and your new class. With no one in the reserve course with him anymore, he felt quite isolated.

You didn't pick up the phone when Hajime called again. He left you a voicemail after hearing yours.

Hajime

"Hey Y/N, it's me. Hajime. I-I can see that you're having fun with your new class, and... And all of that stuff. You look like you're having lots of fun. I just called to check up on you and make sure that you're doing alright. I mean you haven't been showing up at the fountain anymore so... I'm just a bit worried. Please call back ASAP."

He sorrowfully sighed and went right to bed after leaving a voicemail for you. 

He woke up and got ready, you being on his mind for the entire morning.

With his hands in his pockets, he walked to school.

Student 1

"That's him..."

Hajime

Are people... Talking about me?

Student 2

"Hey, Hajime!"

Hajime

"Uh-"

Student 3

"Go! Ask him already!"

Hajime

"...?"

Student 4

"Hehe... Hajime, is it really true that you're jealous of Y/N's ultimate talent?"

Hajime

"Wh-What?"

As they continued to interrogate Hajime, the four students held back their laughs.

Student 2

"So it's true! Hajime's jealous of Y/N!"

Hajime

"I-"

Student 3

"Ha! You should be the Ultimate Jealous Student!"

Hajime's face was now visibly upset.

???

"Hey, shut up, will you? Stop bothering the boy."

The students' grins and chuckles faded, and they began to walk back to class, ashamed.

Hajime

"Thank you... I couldn't have stood up for myself..."

???

"Hajime?"

Hajime

"Y-Yeah?... You know my name?"

???

"Come on... Don't tell me you've forgotten."

Hajime blinked once and saw Y/N when they were still a reserve course student.

Hajime

"Y/N... You're Y/N!"

You

"Yeah! You didn't notice?..."

Hajime

"Oh- Heh, it's just... It's just been so long since I last saw you and... You look a lot different from when I last saw you at the fountain... I-I'm not saying you look bad, I'm just saying that you look like you fit in with you're ultimate."

You

"Really? Thanks!"

Your appearance had changed a lot, as Hajime had said.

You

"Heh, you still look as boring as ever!"

Hajime

"..."

You

"Just kidding! You still look the same, just your hair is a little bit longer now. So, have you been taking care of yourself? You're not depressed since I'm not with you anymore?"

Hajime

"I'm not really depressed, just... Lonely. Y'know."

You

"Hm. I get it."

Hajime

"What are you doing here, y'know, by the reserve course?"

You

"We're looking for a guy in our class named Nagito. He didn't show up, and every time he's unsupervised, he's always up to no good. Have you seen him? He's got white fluffy hair, and he looks just as boring as you... Just kidding!"

Hajime

"Nope, haven't seen him."

You

"Aww, seriously?"

Hajime

"Uh- Y/N?..."

You

"Yeah? What is it Hajime?"

Hajime

"Can you tell me why... Why you haven't been answering my calls or texts?... I'm a little upset that you stopped showing up at the fountain."

You

"What do you mean? I do show up at the fountain! And I'd like to ask why you're not answering my calls or texts either!"

Hajime

"Huh?"

You

"I'm calling and texting, but you never reply to it! Could it be that you added the wrong contact, and you're going to the fountain that's located on the left side of the school?!"

Hajime

"Oh- I... I-I didn't even think about that."

You

"Agh, Hajime! You and your dumb-ass got me so worried!"

Hajime

"Ah- I apologize!"

With your clearly irritated expression, you turned away from Hajime and looked to the left. Hajime also averted his gaze from you.

When you realized he wasn't staring at you anymore, you returned his gaze and sprang into his arms.

Hajime

"Y/N!"

You

"I'm just glad that you're safe."

Hajime's shocked and flustered expression calmed down, then he grinned and just held you in his arms.
