This is a true story, a love story about two girls that happened on campus. From love to hate, from hate to forgetfulness, from forgetfulness to the moment it came to an abrupt end, every step she took was difficult. How to forget someone? It is a complicated process of trial. The ups and downs of sadistic feelings are faintly revealed between the lines of simple words. Everyone has same-sex plots. What kind of person you meet will change your life. In her tears, you will cry with her; in her smile, you will raise the corners of her mouth. Looking at her back, you will feel lost. Is there such a person who also makes you lost? Is there also such a memory that has grown into a secret in your heart? Because it is true, it flows calmly, but leaves an eternal mark in the heart.
