Lee Taemin is a single father taking care of his 7-year-old son. Choi Minho, his boss doesn't think well of him as he is often late and doesn't turn in his work in time. Then Minho looks Behind the Façade.

Jin is like every other parent. He loves his sons. Dearly. Through and through. When life is easy, but even more so when it gets hard.

Hanuel made grabby hands outwards. No doubt for his toy. It had the other man walking close to hand it over. Hopefully Haneul wouldn’t stick it in his mouth like he was apt to do. But that would’ve been preferable over what Haneul did in the next few seconds. His tiny pudgy hands reached out and grabbed a fistful of the other man’s hair; Haneul made a happy little gurgle.

Taemin is a cafe owner who always loves to take order because he likes to see his customer behaviour.   He's single and never fall in love because he always has an aura of  NO ENTRY when someone try to asked him for a date. Until one day he met a very handsome young man with his son makes his heart beating non stop.
