Help find this bl

This bl is about a boy who transported into some kind of game where he should meet handsome boys for the main lead. I dont know what chapter this is but he basically needs money and finds a guy smoking then throwing the cigar butts on streets. Then he took a picture of this guy but he got noticed and got confronted. Then he made up a lot of excuses that he's his idol and that he's his boyfriend. Fast forward he needed money so he ended up tutoring this silver haired guy. And the funny part is that he held this contest for all of the girls in thier school just to find the match. And the price is 3 boxes of chicken. Pls help me
