Han Jisung is the teacher who takes care of your daughters' daycare. You are a single father, entrepreneur and young man. Everyone knows you for being a successful CEO, everyone idolizes you.

Han Jisung is an ordinary, single guy who lives alone. Of all the teachers there, he is the most loved by the children, for knowing how to treat them and act in a childish way just like them...

He always notices that you are a reserved and boring guy, always surly and with a frown.
