DOGMAN

If the ending was already written, do you really want to repeat the same mistakes for the sake of love?

Chou Ke-Chieh was once the lead singer for the wildly-popular Mazhi Go Band, but is now a useless middle-aged man who is no longer able to write love songs. After his wife files for divorce, he is forced to move back to his old family home and live with his father who looks down on him.
At that moment, the time-traveling 25-year-old Ke-Chieh arrives in the present, determined to “rescue” his wretched middle-aged self by changing his unhappy fate.
Little does he know that all the misfortunes began the day he ran away from his wedding.
