It's hard being a single father, especially when you have five boys who are anything but little angels.

Kris has gotten over the death of his wife, but he still hasn't gotten used to taking care of his sons on his own.

Xiumin, responsible Da-Ge who has better control over the kids than Kris.

Lay, who is an introvert and is taking on the effects of puberty badly.

Luhan, the smart yet mischievous ten year old who frequently uses his younger brothers as guinea pigs.

Chen, the trouble maker who makes Kris feel like he's failing at life.

And finally Tao, the cute baby panda maknae who's totally not Kris's favorite.

On the other side of town, lives Suho, newly single father, also with five sons.

After his wife ran away with the milkman, all Suho can think about is how to take care of five kids on his own.

Baekhyun, the puppy eyed middle schooler whose middle name is Reckless.

Chanyeol, Baekhyun's abnormally tall non-identical twin who loves ferrets.

Kyungsoo, the middle child with severe middle child syndrome.

Kai, the child who loves the sun and his Kyungsoo hyung.

Sehun, the maknae who isn't quite normal.

So Suho joins the local church's single parent partnership program, and meets Kris.

Two single fathers, ten kids.

That can only mean one thing: Trouble.
