I’m looking for a manga

Hi I’m so sorry for this because this is really off topic :( so basically I’m looking for a BL manga, of which I could only read the first chapter. So the plot is like the MC A has to work on a project with a black haired and glasses dude (MC B) whose reputation is that he hooks up with every guy he can. So MC A was pretty scared to work with MC B, and once they go drinking and they clear the air. MC B admits that he’s gay, and that this reputation is only due to the fact that he was in love with a former coworker and was being clingy. MC A tells him that next time he likes someone, he should go step by step, and start by being nice and hold their hand. MC B agrees, and ends up holding MC A’s hand, without him noticing that it referred to that.

I really hope someone knows it, and sorry for the inconvenience again. Sorry for my bad English, I’m not a native speaker. Have a nice day !
