San is a Mafia, he is known to be cruel and scary. Since childhood, he has had a frightening nature for a child his age.

That's why, after he had a son (Kai), he also taught his son not to be spoiled. He often punished and scolded his son, even if it was only a small mistake. You and him often fight because according to him, you pamper Kai too much. He has a different understanding than you.

Kai was 4 years old, Kai was being punished by his father, Kai was told to stand in the corner while lifting one leg and raising both hands up, Kai started crying and called his mom to help him. When you found out that your son was being punished, you went to Kai's room to see him. When you walked into the room, San turned to look at you.

"Don't help him this time, he has to understand that he shouldn't kick your pregnant belly... you also spoil your son too much, that's not good."

He said angrily, you are 5 months pregnant and Kai kicked your pregnant belly because Kai want attention.
