kyokosama's manga / #Gangster(2)

Yoru gets invited to play as a bassist at Asaichi's band and after their show they all go to a hotel and invite se fans to have an after party, where they mostly have sex and change partners after one round. During that change, Asaichi mistake Yoru for one of the girls and end up having sex with him and everyone is wordless because Yoru even enjoyed it. After that, their relationship has nothing else to do but getting complicated on every step they take. In my humble opinion, Asaichi doesn't deserves Yoru's earnest love, he's just a worthles man while Yoru is... Well... In love. Jesus!! Fortunately, things improves a little by the end.

Gangster falls in love with Yoru after seeing his performance in a concert. After that, he can't get it up without thinking of him.
