[Two male leads, mutually devoted and equally powerful, contrasting personalities, happy ending, ⭕]
In his previous life, Xie Lingye shot to overnight fame in the entertainment industry thanks to a role that saved a production. Then a powerful tycoon set his sights on him. When Xie Lingye refused to give in, the tycoon had his only family member, his older brother Xie Yunyan, killed.
Xie Lingye spent a year plotting, then personally brought his enemy to his end.
Afterward, he drove a sports car off a bridge spanning the river.
When he opened his eyes again, he was back in the past, on the day he snuck out to go street racing with his childhood friend.
Later:
Xie Yunyan: "You're a student. Where did you get the money to buy company shares?"
Xie Lingye (obediently): "I saved my New Year's money."
Xie Yunyan: "...You only got two thousand in New Year's money."
Xie Lingye (still obediently): "I made it trading stocks."
Xie Yunyan grabs a feather duster: "You're still a kid! What are you doing trading stocks? Get over here!"
As Xie Lingye dodges, he thinks: My brother is so damn "gentle"!
