Looking for Idol Manhws

so I'm looking for this one story where it's basically like every other manhwa with idol plots but basically the group he debuted was a doomed group in the previous timeline (he doesn't belong to that group in the past) because one member was whom had a backer basically treated other members like trash. There was even this one member that's very pretty but because the. trash member hates how he looks he made him dye his hair in trashy colors and made him wear ugly clothes
