Eunhyuk's used to being with five year olds. He's a kindergarten teacher after all. He's not used to being with an adult who acts like a five year old. 

You don't like it one bit when your little sister of 5 years starts talking infinitely about her kindergarten teacher like he was her world when she had a whole sister that was you. And you don't like it one bit when the said teacher is impeccably kind and adamant to let you have fun during a kindergarten road trip.

In which the boisterous kindergartener Cha Hakyeon, the 5000% done Jung Taekwoon, the weird Lee Jaehwan, the Pretzel-lover Kim Wonshik, the forever jealous Lee Hongbin, and the angel-slash-devil Han Sanghyuk wrote a letter to Santa. What would they write?

In which the annoying 5-year-old Cha Hakyeon, the 4-year-old Kim Wonshik and the 5-year-old Lee Jaehwan who had a love-hate relationship, the best friends 4-year-old Lee Hongbin and the almost 4-year-old Han Sanghyuk, and the scary 5-year-old Jung Taekwoon had to go to a school trip to a pig farm. What could possibly go wrong?

In which the 5-year-old Cha Hakyeon was the annoying kid, the 4-year-old Kim Wonshik and the 5-year-old Lee Jaehwan were the troublesome kids, the 4-year-old Lee Hongbin and the almost 4-year-old Han Sanghyuk became best friends for life, and the 5-year-old Jung Taekwoon wanted to remain uninvolved.

A child's play? More likely a nightmare I would say ㅋ
