Chu Wannings beloved

I just had this random recollection of a certain cute scene in a bl manhwa and i don't remember the title


I think i remember it was an M.T (idk something like a school event in Korea??) students were gathered together and drinking. And i think MC was asleep in a room crowded with other students sleeping. Then i think i remember the ML picked up the MC and put him in a couch and slept with him there. Next morning the girls were wondering who was the lucky girl sleeping next to ML and they peered closer to see who it was..
