Ask for the name of a novel

It's a romance novel from the male protagonist's perspective. I don't remember if the male protagonist was reborn or transmigrated, but after he was reborn, he transmigrated into a pretty boy's body. He studied in university and had a girlfriend, but he often borrowed money from her. After the male protagonist transmigrated, he realized that his girlfriend was the sister of the female protagonist in a television series he had watched before.
Before the male protagonist was reborn, he was a contractor, but he had already worked hard. I forgot how he died, but the male lead was extremely stingy. After his rebirth, he dropped out of school and started working at a construction site. During this process, he broke up with the original owner's girlfriend, but later on, he fell in love with this girlfriend and got back together. Later, he gradually developed into a contractor, and then gradually developed. I remember that the author said that she had specially inquired about a lot of information about the contractor, so the story described this industry very clearly.
After the male protagonist was reborn, his family had been messed with by the male protagonist. This made them mistakenly think that the male protagonist was being used as a target for money laundering by the underworld, and they had cut off contact with this group of family members. It was completely close to his father-in-law's family.
There was another plot. The male protagonist and his girlfriend went out together once and encountered a scam. The male protagonist asked his girlfriend to hide at the side, but he robbed the two scammers instead. After his girlfriend found out, she forced him to donate the money he robbed. The girlfriend followed the law and hoped that the male protagonist would not break the law.
