As Yuna was busy chopping vegetables, Jake appeared at her doorstep, flashing his charming smile. "Hi, Mrs. Introv," he said, using Alex's mom's maiden name. "I hope I'm not interrupting anything important. I was wondering if I could borrow some sugar."

Yuna, still unaware of Jake's true nature, was tempted by the invitation. But Alex's instincts were right on point. As Jake left, Alex sat down with his mom to explain the situation.

"Mom, Jake is a bully, and he's been making my life hell at school. He thinks he can just charm his way into getting what he wants, but he's not a good person."

The story ends with Yuna and Alex sharing a warm moment, grateful for their strong bond and their ability to protect each other from harm.
