The truth is, Kenny only used her left hand which was covered by a thick glove to pull the man's hand away from hers. Without anyone knowing how Kennye could break the man's finger.
Ruina and Shin covered their mouths so as not to let out their shrill laughter. The thing is this scene is very funny to them.
And it turned out that it was Shin who won, because Kenny only needed one second to injure her opponent, that's how she's been known all this time.
"Let's go!". Kenny shouted to her two friends while walking and wearing her glasses leaving a crowd of people who were circling the man who was still hysterically holding his hand.
"Shit". Kenny continued with a wicked smile.
"Why don't you just break the masher man's neck? So that he can't even glance at and tease other women". Ruina asked while still holding her smile as they walked towards the parking lot.
