So the manga im looking for is:

-This manga is a one shot (i believe) and possibly grouped with other one shots. The chapter starts off with the girl just coming out of the shower and her bf dumps her. Then on her way home, she sees her neighbor (his name is Hayato i think) who's 2 years younger and he asks whys her hair wet and they somehow end up inside his house. She then tries to i guess rape him (she really wants to just hurt him cuz of how she was just hurt by being dumped). IF YOU KNOW PLZZZZZZZZ HELPPPPPPP!
