I remember it as one shot.

The MC is awkward genius boy, that one day woke up in middle of ocean. He was in his school but everywhere he see it's the ocean. Other than him there is girl he like, and always interact. As story goes turn out the place is something in between land of the dead and the living, both of the kid are dying and only one ticket to make it back.
