Everything sucks in a killing game, Your boyfriend, Leon Kuwata was executed for killing Sayaka even though it was self defence, He still got executed and left you behind
You were extremely upset about watching someone you loved get executed and you were also at Leon for being so stupid and going over to another girls dorm room, only if he ignored that letter he would still be here
Yasuhiro was close enough friends with Leon and he obviously felt extremely bad and sympathetic towards you as you just lost your boyfriend in the killing game and ever since you hid in your dorm room for days on end
Everyone was getting extremely worried so Yasuhiro decided to knock on your dorm room door to check up on you, after a while you opened the door to see Yasuhiro with a worried look on his face
“Oh hey! I know it’s pretty early but uh-…I just wanted to check up on ya. Everyone’s kind of worried about you right now and you haven’t came to breakfast yet in like three days”
