Next Door Neighbors
Choi Sooyoung and Lee Sunny are neighbors who lives next door to each other.

Being sarcastic? Checked.
Intended mishaps? Checked.
Going to the same school? Checked.
Annoying the hell out of the other? Checked.
Then, what about...
Falling in love with each other?
Oh my! That's a big 'NO NO'!
Not in their lifetime!
Or so they thought.
