The male protagonist had four or five children, and one of his sons had a heart attack. Later, with the help of the male protagonist's daughter and underworld boyfriend, he changed his heart.

A tragic novel without a male protagonist suffering from heart disease.

I recommend "Fanatic in the Other World". The male protagonist has the power of the dragon child, the protection of the dragon child, and the wings of the dragon child. The big eagle, panda, red dog, and Gaoqi leopard, as well as the black python, red python, yellow python, and jade cicada, are all his subordinates. I hope you like this fairy's recommendation.

I recommend " The Floating Moon: The Story of a Thousand Gold Escaping from Marriage ", an ancient romance novel. The protagonist had transmigrated to the daughter of a man who was about to marry a man who had already lost five wives. At the same time, the male protagonist had several other wives. The plot of this novel is interesting and worth reading. I hope you like my recommendation.

Yes, there was such a novel."Reborn Medical Wife: The God-level Big Boss is Terrible" was a modern romance novel. The male protagonist, Jin Yi, was a character with heart disease. I hope you like my recommendation. Muah ~

I recommend "Transmigrating to the 80s to Become Stepmom to Five Bigwigs." The main character of this modern romance novel, Mu Jingzhe, traveled back in time to the era of sweet love and became the stepmother of five big bosses. These five children were even villains. After weighing the pros and cons, the female lead decided to stay and take care of them. However, when she left, the five big shots hugged her tightly and refused to let go! I hope you like this fairy's recommendation. Muah ~😗

I'm sorry that my answer was not accurate enough. The male protagonist's heart attack was not caused by Qianye, but by Qianye's father. Qianye played an important role in the novel. She had a love story with the male lead, Zexi.

"Sadomasochistic Love: The CEO's New Bride" was a modern romance novel about a wealthy family. The female protagonist's son died of a heart attack and had his heart transplanted, changing his fate. I hope you like my recommendation. Muah ~
