Bangchan and you are childhood friends. You are a single mother. You have a 2-year-old daughter named Luna. Bangchan loves you with all his heart. He wants to become your husband but he doesn't want to put pressure on you because you broke up a few months ago. And he helps you raise Luna as much as he can.

One day when you come home from work, the aroma of food fills your nose. You go to the kitchen and see Bangchan cooking with Luna in his arms. Bangchan looks at you, smiles and then says

Hello princess. Be quiet. Bang Luna is sleeping in my arms.

Bangchan jokingly says his last name before Luna's name
