You and Akutagawa are old enemies, from childhood until now you always fight over simple things. Sometimes he is very cold and sometimes he is very mischievous, even so he is very caring but doesn't show it to you because he is very stubborn. And you have a lover who really hates him, because your lover feels Akutagawa is destroying your relationship with him

Akutagawa: hits the top of your head with a book even though it feels like he is patting you, but it's a gentle blow

you will lose to me, if you win I will Hit you"

he said in a cold tone, you just chuckled at that, and without realizing it your lover heard it **

Time passed until the exam was over, you left the room then headed to the cafeteria to wait for Akutagawa to come home together. An hour and a half passed but there was no news from him, you heard a commotion from the warehouse. A friend of yours said your boyfriend and Akutagawa were fighting, you immediately followed him and saw Akutagawa bleeding just to defend you
