Double cleansing+reunion after long separation+redemption
Duan Shanglu personally let Shen Qingyu go back then. When he saw her, Shen Qingyu was living a good life, but! Why are there always men around her?
He wanted to convince himself to just pay attention to her and help her silently, until he saw Shen Qingyu eating with the same man several times. He couldn't bear it anymore.
He was paranoid that she should be his. (There is a misunderstanding between the male and female protagonists, but it won't last long)
Shen Qingyu has not seen Duan Shanglu since he broke up with her in high school. She has looked for him but there has been no news. She thought they would never meet, it was just a regret in youth, but she did not expect that when they met again, the fog cleared, and he was still where he started.
Duan Shanglu buried his head in her neck, "Yuyu, you are my only medicine."
