I seriously don't remember much but I think it's a bl. It goes something like this. An idol trainee gets injured or something happens to him or he's been a trainee for too long so he becomes a manager for an idol or actor. And the idol/actor gets into a car accident and the manger guy is asked to take the blame. Sorry I'm not very helpful with the description but I guess it went kinda like this.
Guys recommend me some good bl manga with established relationships like nichijou complex. Recommend me a good list. Thanksssss

It is a manhua or manhwa but mostly I remember it being a manhua. It’s got this straight couple. I think they met once during childhood during some training perhaps? Later the girl due to the orders gets married to the guy… it had this really really good art too
