They met on a train.The uke(?) handed the seme a letter. which had a hotel room. I think the uke said something about handing out letters but the seme was the only one to ever show up. the MC is awkward so handing out a letter to a stranger was his way to meet people. I also remember he has a thing for hands
I think this is the one you are looking for
