Help me find this yaoi

I can’t remember the name but I remember the bottom is a blond with the wolf cut while the top has like dark violet hair. the bottom gets a package from his ex delivered to his old apartment which the top now lives in and we find out they used to go to school together and the bottom accidentally bullied him. then one night the bottom gets drunk and sleeps with the top and now the bottom has to spend 5 dates with the top to make the top forgive him. does anyone know the name? i cant find it anywhere.
