Im looking for that webtoon where top is CEO of hotel chains and uke is manager of one of those.
I think top and uke are HS friends and uke was going to confess to top in a piano room(this is a key place) but he was stood up. Years later they met and uke realized that he was working for top.
I forgot if they pretended not to know each other but it’s a slice of life BL.
Not sure but maybe its Incidentally Dyed By Spring's Love
?
