My Perfect Boyfriend Was A Delinquent In High School?!

Dr. Su Lian watched his beloved Chi Wang die at 25 from lung cancer, his perfect life cut short. Devastated and yearning for a second chance, he met a mysterious master. A miraculous watch was granted: a device that could rewind time. Su Lian seized the chance, leaping back to Chi Wang’s high school days to fix the \"mistakes\" that led to his tragic end. But the refined, calm man he remembered? Seventeen-year-old Chi Wang was a wall-jumping, cigarette-smoking ruffian, completely unlike the gentle lover he knew. Su Lian’s noble mission quickly devolved into a series of exasperated time-loops, repeatedly kicking Chi Wang off walls just to curb his bad habits. Now, with a literal rewind button in hand, can Su Lian tame this wild youth and save his future, or will his attempts at \"tough love\" only make things gloriously worse?
