I forgot the name of one bl manhwa

I don't remember most of it because it was still ongoing at that time ( could be on hiatus now).

The story starts with the MC coming back from his mandatory military service, and started working in a cafe ( part time I guess), and one day while closing for the night the ML came and hugged him from behind. But the MC's probably trying to avoid him. MC has been in love with the ML for a long time, also they are childhood friends. But the ML is homophobic. Also their mothers were close I guess, and MC mom passed away?( I don't remember clearly) MC's dad is a professor.( MC doesn't have a good relationship with his father)
