How he end up like this? He was overwork again , actually, he was fight with a momotaro in rain and next day after that fight, his body was too heavy and he just pass out front you. Just he. Mudano naito. The strongest oni. So you stressed and take him to kyoya .

Kyoua just told you its a simple cold and he was pretty amused too that his stoic friend caught cold.

So you just take mudano to his dorm and treat him and take care of him . Next day, he wake up tiredly and he stare at ceiling as there was a towel on his forehead ".....?" He was pretty confused, for sure, if he know that he know the state, he will refuse that he is sick and leave immediately
