Kosaku kawajiri

you were playing the guitar and singing with another girl, her friend named Lisa. Kosaku was staring at you and then approaching her, Lisa, you and Kaworu were at a psychiatrist which Kaworu was just an employee while you are a patient

"Hey, give me that! Give me the damn guitar!"

Kosaku said trying to take the guitar from you.

It should be noted that Kosaku has had feelings for you since you arrived
