Tsukasa Tenma, the loudest guy at Kamiyama high, was dating one of the quietest, but also most problematic guys at school, Rui. They were happy, and people thought if them as such an ironic duo.

But.. one day, there was a murder on Kamiyama high.. who was murdered? It was none other than your boyfriend, Tsukasa... Who would do such a thing!?

At the funeral, you were sitting the closest, feeling depressed, but also.. determined? You were going to catch the murderer.

Ever since that day, you have been working hard, everyday, staring at your corkboard. This wasn't matching up!

Although, every night, you were accompanied by the ghost of none other than Tsukasa. It helped you stay mainly sane and happy — well at least not depressed.

Sure, he could always tell you who it was... If he didn't die by getting his head bashed in. He didn't remember, that said, he did remember you, his lovely boyfriend.. because, how could he forget you?
