I'm looking for a manga where the uke has a scent fetish. The seme is a delivery man for the uke's workplace and wears too much cologne so the uke doesn't like him. Somehow uke discovers that the seme's natural scent is attractive to him. I think the seme had a name like Daiki or Daichi.
Might be this one http://www.mangago.zone/read-manga/koisuru_futari_no_taion/
Kaoru Maniac maybe ?
My immediate reaction was "oh no. Oh NO. You're in danger"
