At home, if the Class Belle made him unhappy, he would throw a punch if she said too much.
Tang Huai talked back to him, and instinctively he wanted to resort to violence. If it weren't for Tang Huai, he would have thrown his clenched fist.
Why must he endure the pain of being a eunuch, just because he's a man?
He can earn money, he has his own career, why can't he live like a normal man?
He doesn't want to be a eunuch!
He resorts to violence against the Class Belle because of the resentment he harbors towards her in his heart.
If she hadn't thrown a tantrum and left on the motorbike that night, he wouldn't have chased her, and wouldn't have fallen, and wouldn't have had the most important part of him crushed by the motorbike.
Since that incident, it never rose again, and he never had a normal experience since.
He has the desire and the courage, but not the ability.
