[@Lemons] Ok, my thoughts for Haru are he's a pretty social guy, so he might also be part of the student council and/or class rep. Outside of that, he is a huge photography buff. Before school, after school, he always has his camera to snap a shot of something. He'll sometimes whip out his phone during school hours to capture something that catches his eye. So maybe he's like the PR/social media person for the school since he always takes great shots. 

Maybe the two could have met during a school event. And sometimes he'll bring his little siblings with him to some events to keep an eye on them. 

I'll post his CS either today or tomorrow
