Forgotten Title BL novel. Please help me find this novel!!

Hello
I'm sorry if the post is messy but it is my first time writing one.
i'm looking for this BL transmigration novel with a system. this is what i remeber from it.
so the mc is the best freind (childhood friends) of a boy and a girl and they have an arranged marrige, but he has a crush on the boy(male lead). The story starts with the mc in a changing room trying on cloths for the wedding, the is girl waiting outside, when they get outside the girl gets hit by a car which is the mc's stolen car, well she dies and later on that day the male lead goes to where the mc is and shoots him because he thought that he(mc) is the reason she is dead since it was his(mc) car.(i think the male lead knew the mc had a cursh on him)
the mc starts over and wakes up back in the changing room and and asks the system to stop time, but he can only do it for 5 minutes. so he cries for 5 minutes. He walks out and the girls sees that he has been crying, anyways the go out again bur he pushes her out of the way, then he ends up in a hospital room. the ML does not trust him.

i think but i'm not sure if it is from the same novel but the ML and girl are from 2 different mafias? with aranged marriges for generation.

i think there is a scene where the ml and mc go to the gym.

anyway it ends up that the girl has a girlfriend and it is a fake marrige, the ml takes care of the mc (cuz he is hurt and can't walk from the injury)

I know it is a lot but please help me find it

fhjsjf It's intresting and I haven't read this yet! Maybe drop some clues where you read it? Cause some can be found in wattpad or you found it in novel updates? Hnnnggg Imma camp too!

This one is interesting.

But just to clarify is it a trasmigrating or a rebirth story? From the description it's more of a rebirth with a system not a trasmigration.

And I feel the angst in the air.

 

I don't remember where i read it that is the problem.

 

I'm not sure since i think this was the first arc of the novel.

 

It's QT?
