There are comments complaining about the author writing the characters' pasts, especially Mincheol's, but I think it's important. It gives the character more depth and makes the manhwa more complete. Seeing his past doesn't mean you have to feel sorry for him or anything like that.
Omg now they have a 5 star rating corn bcuz of the camera in the car outside the garage ლ(´ڡ`ლ)
