KanoBitch ~Kanojo ga Bitch ni Natta Riyuu~

Synopsis

...... I have no hope. I hate everything, I want to die. What made me this sad is... Tell you what, I saw my childhood friend Mai who is my crush was walking with a man. She linked her arm with him. That scene made me think that she has already gone through this and that with him. When the f*ck did she find a boyfriend? Are childhood friends are supposed to become lovers? "Hello!" So the cause of my headaches comes. How could I even face her, dammit!! (Taken from DLsite description)
