pls help

so i was doing some housechores when i randomly remembered a bl manhwa that i've read years ago (4yrs ago), its about the bottom is an idol and their concept is something like devil achuchu and the top is a fan of their group and he is his bias, he's like the typical black haired ml huhuhu, it's artstyle is kinda a softy one (as far as i remembered) the uke n top (sorry i forgot their name so i had to use this as their identity) became friends i think but the uke didn't know that the top is a fan of their group, and i also think that the top made a twt acc to post about the uke's career or he's just fanboying. help me find it pls huhuhu and another info, the top has a room full of uke's merch, from the limited to the latest merch of them idk if these info would help but i'm desperate so yeah
