Falling in love hurts.

But falling in love with your best friend is even worse.

Especially when you'll just be his "winglady' or tinkerbell for the rest of his life.

Tinkerbell would always be by Peter Pan's side. Even if she fell in love with him, but in the end, she's so small that his love for her is also small.

Kyungri is Kris' tinkerbell. Kris doesn't know it, but deep inside Kyungri's heart, she knows. she just can't accept it.
