Accompanying each other for seven years, what she waited for was only the phrase that he would not spend the rest of his life with her. She put on the ring she had prepared, but the other party only took it as a means for her to make him stay, not taking it to heart at all.

Seven years of devoted companionship finally made her understand that her true heart must be kept for those who know how to cherish themselves.
