Can you guys help me find this manhwa???

So, for the MC, he was a new actor and one of his movie when famous(thats what i remember), he is older just a few years. And for a ML, he was an idol and his group is famous too, he is younger for a few years. I think i was wrong in their first incounter, i think they met in a event like yk the award show in korea? Like the best actor & actress also for kpop group. Thats where they met. Then their second incounter was the like meeting for their up coming vlog, along side with other actor(middle age man) and an rookie(?) idol. And the director for this was also famous director. After all there talking, the next few chaps. starts and they play games(idk for what purpose) in the end, mc and ml become roomate. There is also other scene where mc secretly become a fan of ml(dont know how) and that when he start listening to his song and watching their cheography. Another scene, they play games, guessing a kpop song. Mc and ml loss(theyre both partner) so the consiques is. They can go as far as they want but they got little budget while the other team got the opposite. That all i remem. Also its a fluffy manhwa and its bl like, thank youu
