Searching for a BL

Searching for an omegaverse bl...Mostly it's a Korean manhwa (could be wrong)...I don't remember much but there is a part where the seme had invited his friends over and is introducing the uke... The seme receives a call and leaves then one of the friends start telling the uke about the seme's ex with whom he had bonded but they broke it, which disturbs the uke so much that leaves the room and rushes to the bedroom on the second floor. The seme comes back and begs him to come outside, but the uke doesn't.
