In Middle Age, the System Forces Me to Be Young and Reckless (118 episodes) - AllShorts

Thirteen years of marriage drained his youth and made him a failure in everyone's eyes. The moment the divorce agreement is signed, the "Young and Reckless System" activates: the more boldly he lives, the younger he gets. Everyone waits to watch this balding, paunchy middle-aged man hit rock bottom, only to see him regain his looks, pay off his mortgage, mend his family ties and reach the top in business. As his ex-wife regrets, a female CEO proposes, and the truth about a misplaced love from thirteen years ago comes to light, Su Mu refuses to return to any life others have arranged for him. His second youth has only just begun.
