Chuuya knew how prone Dazai is to getting sick. He's either down with a cold, fever, or smth else.

They both were sitting on the couch, Dazai curled up on one side. Chuuya steals some glances at Dazai as he watches tv. He notices how he looks a bit paler than he actually is. And the fact Dazai is wrapped in a blanket while the room temp is rlly warm, concerns Chuuya. After a minute, he reaches over and touches Dazai's forehead, feeling him burn up.

"Youre burning up, Dazai.." He sighs.
