Basically MC is an ex-idol and one of his old members had drug/alcohol problems and that same person ended up forcing a drug(the same drug the ML is tracking down) on MC, years later MC meets ML and ML tries figuring out how to relieve the side effects from the drug MC took years prior, wanting to make him enjoy life again
I think it's also kinda hinted that ml may be hiding his identity a lil bit?he was into the drug thing before he even knew what the mc went through and he's affiliated with the doctor and that really got friend of his,the club owner girl and him also we're like willingly luring this drug out through their club adjustments

Can someone give me a run down if the plot because I’m fucking lost in the sauce. Maybe I wasn’t reading closely enough, but please help TT
It’s was all fun and games for me until the seme was seeming to be tracking down the drugs or something like TT
