A pack of Cherry-Lime Chewing Gum. That was all it took to reunite two lovers.

Okay, so maybe not completely reunite them, and they weren't exactly lovers, either. Park Sanghyun and Song Minju were two teenagers, best friends too, hopelessly in love, and both too shy to confess. Put it together. What was your final result? That's right! No couple.

It's been five years. Sanghyun is now Thunder, lead rapper in MBLAQ, and Minju has recently moved to Korea.

Unfortunately, time has taken its toll, and Minju does not remember her first love, who is still searching for her. 

Fate (with the help of sweet and sour gum!) will bring these two together again. Maybe not so easily, though.
