Kimi no Kiss Ga Naiteiru

Haruto, a second year high school student, has two secrets. The first is that anyone he kisses loses consciousness and their memories of the preceding five hours. The second is darker and more bloody, and binds him - like the friendship bracelet he wears - to first-year student Umi, although she cannot remember why. Secrets, like memories, can come to haunt you...

Debut serialisation by Minato Ayase.
