Trying to find a BL manga

I’m trying to find a BL manga where the ML asks for the MC’s help with a baby because (i think) his wife died, and the MC and the ML live together. The MC is in love with the ML but doesn’t want the ML to know, but after a while living together the ML has fallen for him too.

Now this scene that i remember vividly is the reason why i’m searching for this manga: one night both of them get really drunk, and the MC (by muscle memory at this point) goes to put the baby to sleep in the baby’ room, and the ML makes his move and tries to kiss him. the MC is about to reciprocate but last second gets sober i think and pulls away
