Kai who isn't so great to be around with, fell in love with a girl, Hye Jung, who's in love with Suho. 

18 year old Kai, just wants his past back. To renew everything he regretted.

Everything that caused him to loose happiness and joy in all the fun things.

Everything that made him cold. Will everything remain the same when he meets her?

Mr. Nice Guy, Suho, never really wanted anything. Unlike Kai

who's always depressed Suho would always be the energy pill.

Her energy pill to be exact. How exactly will he get by when he

misses her?

Hye Jung, a girl who's clumsy about everything. Annoying

at times. Suho's secret admirer. What happens if Suho 

finds out? Will she be happy or sad?

Side-character(s):

A mid-year transferee, Jung Yong Jung , (better off known 

as Nicole) ends up being used for a reason people

wouldn't really understand in which she becomes partners

in crime with the guy.

14 year old Kai seems very intimidating, but turns out to be 

a better example than 18 year old Kai. He's a very cheerful

kid until he learns how he really is.
