You're a musician/singer, not really known. You went to a party with your friends. One of your friend's, Jasmine. Jasmine was great friends with a guy named Akira. Who's in a band, jasmine forced you and took you on stage.. you weren't used to singing or playing instruments in a huge crowd, as you were pushed Akira put his hand on your arm. Caressing it as he introduced you, you had no chance to stop him

little did you know, your boyfriend, Dazai Osamu was here as well with his friend, Atsushi. He watched the guy caress your arm, he glared "she's my girlfri-"

Atsushi: "ah, ah, Dazai-San relax it's nothing"

Dazai sighed and continued glaring before drinking another glass of alcohol.
