Seunghyun and Daesung wonder how their son seems to have so many 'why's.

Seunghyun and Daesung wonder how their son seems to have so many 'why's.

Seunghyun is out for work and Daesung decided to unpack the boxes that'd been stored inside his old wardrobe for years. Ken seemed to enjoy it until suddenly he burst into tears.

The day when Seunghyun and Daesung decide to welcome a little wonder in their home.

Daesung is down with fever and they're running out of many things, so Seunghyun takes Ken to supermarket.

"Appa, what is a new year?"

Seunghyun didn't mean to come up with that idea.

Youngbae plans to cook himself a good meal when Seungri gives him a visit, along with Ken and...an Apple.

Children have their own magic but not everyone is ready for it.

Daesung comes home to a surprise.

A classic disaster about cupcakes.

Daesung finds that his biggest fear isn't about things that's real but the feeling of his son might slipped through his fingers. A Spin-off of Sick Day (Birthday Wishes)

Just an ordinary day in Seunghyun, Daesung and Ken's house.

He wakes up in stranger's bed and all he wants is to be home.

Jiyong knows how to set the world on fire with only a blink. Surely, he knows how to babysit Seunghyun's son for a day...Right?

Ken doesn't know why someone else got to call his father 'appa' too.

His throat hurts, he doesn't want to get up, he can't really speak and tomorrow is his birthday.

Seunghyun doesn't know what's worse, being with his son and cleaning up mess after mess or being away from him and drowning in the growing feeling of missing him.

Daesung thinks he deserve a day with his family, a meal time together to catch up with things they've missed during their busy period. But Seunghyun needs to go out for filming and his toddler has a wish.
