Keigo has always been the easy type of guy and one day it turned out to be his biggest flaw when his one night stand confessed being pregnant. Unfortunately the mother of his son died after giving birth, leaving Keigo alone to face the obstacles of parenthood. He never thought he’d want or have children but now there was no other choice.

And even after years the way of parenting felt like a first time experience for him when his 4 year old drowned his toys in the toilet or fell into Mud puddle.

Lately he’s been noticing someone new moving into the apartment next to his. As curious as he was, he couldn’t resist but to knock.
