He had never been much for socializing from a young age, especially with girls; he felt that getting involved would bring a lot of trouble.
Thus, his attitude towards girls was always very cold, and he'd even resort to harsh words to shake off the harassment from those girls.
When he was still in school, he made a whole bunch of girls who admired him cry and run away in fear.
For instance, a girl who claimed to be the campus belle confessed to him, and he would say, "You're even uglier than me; is your title of campus belle something you bought with money?"
Consequently, the campus belle cried because of him.
As he grew older, he skipped grades and went to college, where a female classmate expressed her feelings for him.
He said, "You're already this old, how could you still shamelessly say you like me? Don't you feel embarrassed? Wishing for a May–December romance?"
The female classmate, left without a shred of self-respect, was also driven away in anger.
