I'm her Onii-sama

After leaving the internet cafe, Alex was running towards Lilitth's school, but being really worried, he decided he had no choice. Alex saw a guy riding a motorcycle, he knocked the guy out, place him on the sidewalk, and wrote a cheque that was more than the amount used to buy the motorcycle.

When the people saw what Alex had done, they started panicking, some even tried to video the event, but were unable to do so, since Alex did everything smoothly and quickly. By the time they got their phones out, Alex was already gone.

...

Even in a motorcycle it took Alex a few minutes to get the school. When he finally reached Lilitth's school, he noticed the lack of people in the vicinity. He then saw a blockade, and some of his dad's men.

Alex could already pretty much guess, what had happened. His dad dotes on Lilitth to an extreme, and Lilitth messaged him that their dad was going out of control.
