Chen Qiao and Han Xichen were each other's first love. After graduating from middle school, Chen Qiao gave up her relationship with Han Xichen for the sake of her studies, never expecting it to become the regret and heartbreak she could never escape for the rest of her life. The pain even gave Chen Qiao chronic stomachaches. They met again several times, but neither of them was the person they had once been. She finally found him, but he was no longer the one in her heart. In the end, they each married someone else and chose to let go of the past. At last, they understood that loving someone you can't have is the norm, and living in the present is what matters. Even if you could return to the past, you could never go back to how things were.
