Lost the tab

Just read a bl webtoon about this guy who worked at the bar, where he had like codewords and rules with his lovers but didn't want to commit to a relationship. Then he met a student when he got back to university after a break which he had to do because of coming out and his colleagues reacting to it in a shitty way. Etc. He fell in love with him, that suoer timid student is surprisingly also gay and even got tattoos to be cooler for the mc.
Do you know the title?
Thanks!
