Sojin is sure that he'll never end up with his greatest idol, Onew. However, through a rather random turn of events, he comes face to face with Shinee in a way he never could have imagined. 

Sojin (OC) begins his first year of university and falls for Kim Wonpil in an instant. Unfortunately, things get more complicated once he literally becomes lovesick and begins to cough up flower petals. Sojin finds that he has limited time to make Wonpil return his love or face an untimely demise. Based on the Hanahaki Disease, where the victim dies from blooming flowers if their love is unrequited.
