The male idol who suffers from '8th grader syndrome' and how his teammates deal with it.

DW: I want to make chips from your light~.~

WH: My nose is shining..

SY: I also shine.. I shine too bright.. I have to control my light..

SJ: Dangerous.. Inspirit, did you get a heart attack?

SG: Yeah.. Totally.. I totally want to hit your heart..

HY: Yeah.. I really want to hit your heart for once.

SJ: Men who work are sexy. That's me.

WH: Thats Mangwon District^^ Such a familiar place..

Second row: 

SJ: #JjongCottonCandy Do you like it?

SG: I like it!

I'm rooting for Sungjong's 8th grader syndrome.

8th grader syndrome: 

A period of time when one is searching for oneself. Can also be when one wants to act more adult-like. Often results in shame, disgust and the wish to erase that period of time from existence in later years (urbandictionary)
