Do you know this?

(so ... I have already tried to ask but no one can tell me. So I will probably continue forever ....). it's a webtoon and it's yaoi. Uke and Seme meet in the bathroom of the company where they work. they talk from bathroom to bathroom and don't know each other's faces. Seme is an important person at work while uke is a normal employee. they become friends and uke is happy with the current situation while Seme has fallen in love and would like to know him better. the two move away (I don't remember if because Seme tells him his intentions or because Unke doesn't have time because he is annoyed by the ex (maybe)) At a certain point the two meet: they clash in the office (if I'm not mistaken). and Seme recognizes uke's voice. and nothing .... I don't remember anything anymore.
