Summer vacation is all about family fun and competitive dads. Join the Moon family and the Kang family as they grill out at the park and dads Byulyi and Seulgi as they grill up to be the best Dad of the summer. 

Also Wheein and Hyejin refuse to be nice to The Enemy aka cousins Sooyoung and Yerim.

Youngsun and her sister Juhyun are just happy to get the family back together again. Maybe they'll finally decide on who should bring the family famous pot pie to family events. Not for nothing but their mother DID give Juhyun the recipe....not that it means anything at all :) 

And Seungwan is too mature for childish things, that's why she's reading MATURE things like Catcher in the Rye and not playing with her baby younger siblings.
