Forgotten Title Tell me if you know

Hi!
I read a manhwa/manhua which is based on martial arts and it may also include cultivation. The story takes place on earth either in korea or china. Mc has been assigned by his fiancee's dad to protect his daughter (MC's fiancee). Mc is super strong and he acts like a carefree person. There's also car racing, auction and there's also a scene where the friend(girl) of MC's fiancee tests MC's strength. Or something like that. If anyone knows the title of this manhwa/manhua then tell me.... Thanks in advance


2= Also there's another story i wanna know the title of. It is similar to manga( my Japanese sisters) in which mc has two sisters who are idols and he is their manager. There's eroticism and romance in the story. The story may not be japanese. Both sisters and the brother are students in same school

This just made me think of katekano idol sister, but that’s a hentai with 3 sisters.

 

No. I don't think it's this one. The story I'm looking for could or couldn't be hentai/borderline-h manga but it has only two sisters and they are the ones to always jump on their brother.

 

1 sister the other two are the sister's friends.

 

AHHHH I suddenly remembered, don't know if this is the one since it's about gravure models instead of idols but I think I know what you're talking about. It's about 1 sister and her best friend who both become gravure models and both of them also have a crush on the brother.
It's called Schoolmate, is this the right one?

 

Nope. That's not the one. Both girls are idols and they sing on stage. They study in same school.But thanks anyway

 

Anedol - Onee-chan wa Idol (hentai)- the only one I can think of.

 

Ok forget it. I'll give it a go.
