Ji Rendong always knew that Xu Mingzheng didn't love him, but he just wasn't his favorite. Secondary love is nothing compared to true love.
In the past, she thought that the girl he loved most would not be with him anyway, so she would just stay with him. Later, Xu Rendong realized that she was still greedy after all, and she couldn't bear that the person she loved most loved someone other than herself.
Jealousy and unwillingness left her feeling stuck in her throat and exhausted. Finally let go, let go of Xu Mingzheng and let go of myself.
Concept: Love is mutual.
