A normal, bug-eyed teen (namely, Do Kyungsoo, 18) vs the "guy of his dreams" (Kim Jongin) also known as his dearly beloved neighbour who apparently "doesnt know Kyungsoo exists?" or... does he? :)

*FLASHBACK* "You may now kiss." I took that opportunity and spun Kyungsoo into a tight embrace before kissing him passionately. Up to this day, i can still remember that kiss. His quivering lips against my soft lips, and his watery eyes that found love in mine, and his arms wrapped around my back as a form of security.

How do you react after meeting your extremely attractive childhood friend, the one who promised to marry you.. until he moved and met you again at a most unimaginable circumstance at the age of 17, as a young entrepreneur who's worth millions? And you, Do Kyungsoo... the neighbourhood kid, the smartass at school, the undeniably talented singer who doesnt want to pursue his career?
