Kai, your ex boyfriend. He dump you with his son in your belly 5 years ago

It's raining outside, you we're playing with your son also preparing the dinner. Then you heard a knock on a door

your son running through the door and open it, you're in hurry to the door and saw Kai was standing outside the door wet

"Mommy look! There is someone look like me standing outside! Hm..but he's taller.." your son said.

"Hey..it's been a long time.." Kai said while looking at you."
