MTL - Seventh Year of My Secret Love for You - Chapter 10

A Hentai World is a Dangerous Place, Especially if Your Best Friend is a Hentai Protagonist and You Are a Trap.

“Honey, be good…Give me your phone…”

“No, no!” The internet-addict girl clutched onto her phone, determined not to give him.

The handsome and noble man slightly sighed. He lowered his body to hug the girl.

“You’re not listening again, hm?” She immediately handed her phone over cowardly as he said so in a clear and distinct voice.

He was the eminent and noble Master Li, a powerful figure in the business world.

She was just from a normal family that suffered from her stepmother’s schemes, a pitiful girl.

An accident made him appear in her world.

Since then, everyone in S City knew that Master Li had a treasure and cherished her dearly. He feared that she might be wronged in the tiniest bit. He will personally tutor her in her studies, personally be her training partner in video games, and even reserve the movie theaters for her movies.
