Trying to find a BL webtoon help

I cant find it for the life of me.

Its a Korean webtoon (I'm 90% sure)
BL genre.

Both the MC and ML I'd say are manly built, ML has lighter hair and MC has dark hair and think he is a bit tanned.

It starts off with MC going to a high school reunion thing invited by a guy(lets call the other person douche bag guy) who both the MC and ML knows.

MC meets ML in bathroom at reunion and greets him but ML pretends to not recognise him.

MC and ML knew each other in high school, ML loved MC but MC disappeared after a death in his family during high school(think it was his grandma?) with no contact to ML, the ML also decides to go abroad in the end.

ML essentially lied about not knowing MC and after MC was fired from his job and the douche bag guy(who I think is the son of the owner of the business MC worked for) from the reunion told MC about how the ML planned to meet him. MC confronts ML, ML comes clean and cries and it all comes out that he loved MC. its all sunshine and rainbows the end.

It was a pretty smutty webtoon If I remember correctly. but that's all the details I can think of.
