It Happens Somehow / Mankitsu Happening

The main character of the hentai anime "Something Happens" Oyamada Keiti is an otaku to the core. After a series of dismissals from various jobs, fate finally smiled on him. He was invited to work at a manga cafe where every employee is a beauty. Among them he discovers his childhood friend Suzukawa Rei. Keiti tells her about his terrible affliction: when he meets an attractive girl, a hardened pervert awakens in him and everything ends in hard sex. He loses control of himself, and it is this fact that prevented him from staying at his previous jobs. Interesting, how long will it take before Rei's fortress itself falls?
