What do you do when you deeply love someone?
He has loved her for ten years, but has been watching her from behind, protecting her, waiting for her to grow up, and waiting for her to bloom.
For ten years, he weaved a protective net for her, hoping that she would live a happy and peaceful life in the net; ten years later, he took on all the darkness and nastiness for her.
He gave everything for her, gave her a superior life, allowed her to realize her ideals, and stood at the top of her career hand in hand with her.
