The man was not expecting her kick, so he did nothing to dodge. He ended up falling into the ground. Once he was on the ground, the other men all became more alert. They knew that they had to take Lena seriously.
A few of them ran to attack Lena all at once, but Lena successfully dogged their attacks. She hit them all with kicks and punches, and they also had trouble standing back up.
She quickly got bored of fighting them. They were too weak. She wanted to vent her emotions and instead got attacked by weaklings.
Lena did not think about how unusual her own abilities were. She barely knew anything about fighting, and yet she was able to take on multiple men at once. She did not even try to ask how.
Lens just accepted it, and seeing that the men were getting back onto their feet, she decided to beat them all over again. She was really in a bad mood, and nothing could calm her down.
After the second round of beating them up, she began to feel tired. She decided that it was finally time to go home, so she walked back the way she came, and got into her car.
Then she left to go home. She completely did not notice that she hurt her hand while beating the men.
