help!!

I read this a long long time ago and now I wanna read it again.

so It was a bl manga/manwha/manhua and it took place in an office setting. the mc occasionally went to the bathroom where he enters a stall and talks to another office worker who's in the stall next to him anonymously. The anonymous office worker suggests to reveal themselves to eachother and mc disagrees. later mc and anonymous office worker accidently meet in the office and the mc starts avoiding him and ignoring him.

that's all i can remember up until that point

i think what happens next is that the anonymous office worker gets sad and he tries to mend the relationship with mc

please help me find this !!
