Lure and Sink: Scumbags Always Want to Get Back Together with Me

Two male protagonists + reunion after a long absence + some college campus memories interspersed in the plot + double A in the shopping mall + love from the affectionate Mr. Chi Chi Yanchen (attack) and Song Ci'an (sufferer) are surprisingly close. Elementary school, junior high school, high school and university are all in the same school. One day Song Ci'an stopped him "Chi Yanchen, date me!" Chi Yanchen nodded slightly, "What's the reason?" "You look good." "Okay." Song Ci'an didn't expect him to agree so happily. He didn't know how to love a boy and he put his whole heart on the line, but what he got in exchange was betrayal! He didn't give Chi Yanchen a chance to explain, so he accepted his father's suggestion and decided to go abroad. Five years later, the two met again at a cocktail party. Song Cian was dragged into the toilet and thrown against the wall "Do I have anything to do with you? Let me go?" Chi Yanchen, smelling of alcohol and with red eyes, lay in his ear and said "I'm sorry for not protecting our feelings." Song Cian still relented. After taking care of him for a night, he got stuck. Who will tell him that he is still the aloof top student he used to be?
