Never expect to come on top in a verbal war with a woman, it's pointless. Especially when the woman is the scheming vice president of the student council.
This is turning into a catfight, and Seventeen is smart enough to know he can't win. He quickly changed the subject and motioned towards her to escalate, if she dared.
Since the other party is acting arrogant, Rebecca, of course, won't choose to forgive.
The advantage of a girl's physique lies in their speed. Rebecca took a fighting position, similar to the traditional stance of some ancient martial arts. Her petite form sprung forward abruptly, launching a flurry of palm strikes. Seventeen hardly had any time to react before a series of crackling sounds echoed, and Rebecca's strikes had hit him directly.
