I love Mao Mao! It's such a cute and aspiring show. I wonder if his sisters gave him those scars? I've had this theory where his sisters decided with the golden weapons they were gifted decided to turn away from the family heroic legacy and became villains, due to their father spoiling them and Mao Mao tries to stop his sisters only for them to beat him as they had always seen him as a pint sized loser, and their father a deadbeat smaller loser. Now Mao Mao will fix their family by stopping his sisters.
