A despairing memory (Danganronpa Trigger Happy Havoc Fan-fiction)

Truth be told (Chapter 3 part 2)

I headed back where Hina and Makoto were already there. Everyone arrived not long after. 

Sakura: Hina!

Yasuhiro: Huh? I tought she was sick or somethin'.

Sakura: Are you feeling better already?

Aoi: Y-Yeah... I ate a few donut, and that really helped a lot. 

Makoto: You do love those donuts... 

Celeste: But... wasn't it your stomach that was hurting?

Aoi: Well, my stomachache kinda made me hungry, so... you know... Er, ahahaha... I guess my memory's kinda fuzzy lately... 

Hifumi: They say that a goldfish will eat however much food you give it, even if it's about to burst. Miss Asahina's pretty much the same, it looks like. 

Aoi: Hey! You of all people don't have any room to talk! 

Sakura: Anyway... I was worried about you. 

Aoi: S-Sorry... 

G. Jill: Besides that, you-! 

Aoi: H-Huh..? 

G. Jill: Jeez, your knockers are HUGE! What the heck, did you convince them to double up on milk production!? 

Sakura: Stay away from her, fiend. 

Yasuhiro: A-Anyways... first thing's first, we should talk about what we found. Right, Taka?

Taka didn't say a word. It was the first time I saw him since the trial. He was standing there, dark circle under his eyes. His positive energy. Gone. He's lost the friend he made here. He was quiet lost in his thoughts.

Yasuhiro: Riiiiiight. 

We all discussed a bit about what we found. Into the discussion, Yasuhiro mentionned that Byakuya was at the library and well Jill didn't wait a second to go there. 

Makoto: Hey, um... can I tell you guys something? I found something that's kinda been bothering me. 

Kyoko: What is it? 

Makoto: I found this weird picture in the repository. Appenrently Monokuma took it... 

Aoi: A weird picture? You mean, like... dirty!?

Makoto: No, not that kind of weird. It was...  a picture of Leon, Mondo, and Chihiro all together. 

Kyoko: Those three...? 

Makoto: And the three of them were... laughing. 

Hifumi: It showed the three of them together, laughing? When could it have been taken? 

Makoto: And there's more... In the picture, there weren't any metal sheets covering the windows.

When he said that I thought about it him once more. Chihiro...

Sakura: Then... the picture wasn't taken here?

Celeste: But I don't recall hearing anything about them knowing each other before coming to this school. 

Hifumi: You probably just imagined it! Monokuma cast a spell on you!

Asu: I don't think that's it...

Makoto: No! I saw it, I'm telling you!

Aoi: But if it wasn't taken before we got here, or *after* we got here...
