Looking for a certain Yaoi Manga

Okay, so all I can remember of this manga are short bits, this may be a one shot.

Parts I remember:
1) Seme (I think) leaves for some reason
2) Uke plans to sleep with girls while Seme is away
3) Uke starts to get lonely; starts to clean the apartment; only smokes outside
4) Seme returns and Uke threatens him with a knife for leaving him
5) Turns out Seme was stalking Uke this whole time.

Please, help me find this manga.
