Sungyeol did not have a happy childhood and live in the shadow of the past. When he thought that his life was perfect, that he could almost able to forget the past, his worst nightmare came back to hunt him. Worst, proclaiming his love for Sungyeol.

That person was none other than Kim Myungsoo, the spoilt brat in his elementary school.

I wish I could go back the time... where I can fix the things the way it should be. -Myungsoo

I'm going let him feel the way I felt last time, a million times worst. -Sungyeol
