Unforgettable

Lee Minhyuk has done so much for his girlfriend, he 's practically gone through time to be with her and he's taken care of her with all of his strength, but when she meets Wonho everything he's built starts to come crashing down and he can't think of any way to fix everything that's been broken. Watching the love of his life get torn away from him is hard enough, but he couldn't bare it if she forgot about him like all the others, if he became one of the ghosts he had made others into not so long ago.
