Alice's Favorite

Im pretty sure its a oneshot, but one of the guys died, and the other one apparently can see his ghost now (and its not imagination or hallucinating its actually his dead lover as a ghost) and i only remember that at the end the ghost lover gets a note or something saying something like "ill join you soon" or something meaning that the alive lover has gone off to commit suicide. After that the ghost lover starts crying saying how you dont become a ghost if its suicide.

where the main character can go back into time if he jumps into this certain river, and somewhere along chapter 1-2 he finds ways to not let his bestfriend die cause by a truck. I think his name is saiki? I dunno I forgot the MCs name (It's not Saiki psi kusou tho) XD

Seme adopted uke after uke parents die, uke been doing housework all the time while he was in love woth the seme, then one day he overheard seme talking to the phone, misunderstood, and thought that he was troubling seme. Uke ran away from home but seme brought it back. I remember that the uke wanted to eat yakiniku
