Are there any modern novels where the male lead is an assassin?

He only saw half of it and remembered the following:
The male protagonist was a killer who came out of a training base (the training methods were very cruel, and the last one was left after 13 children killed each other). He could use the ability of ice to kill people. The female lead was a singer.
There was a more detailed one. During the female lead's concert, an assassin wanted to kill a rich man. When the male lead found out about it, he sent a note to the assassin. On it was written,"Do it after the concert. Otherwise, you'll do whatever you want." That was all he remembered. Please help!
The female singer had an older sister who was a white-collar worker. She often went to the bar at night and was once saved by the male lead. The male protagonist's genes had been changed. At first, he had been dealing with ice and could not live without it. Later on, after being in contact with ice for a long time and becoming familiar with it, he could control the ability of ice. The main weapon used to kill was ice.

😋I recommend "The Rise of the Wealthy Class, the Return of the Bright Queen" to you. This is a modern romance novel about a wealthy family. The male protagonist is the third-ranked assassin of the assassin organization Hell, while the female protagonist is on a mission to assassinate the male protagonist. However, due to a mistake, her life has entered the same track as the male protagonist. The male protagonist treated the female protagonist as usual and doted on her to the extreme. It was already a favorite novel, and the male protagonist doted on her even more. He doted on the female protagonist a little too much and was about to come out. It was very suitable for readers who liked favorite novels. I hope you like this fairy's recommendation. Muah ~😗
