I'm supposed to become the valedictorian of the state, but I decide to not attend the SATs.

At the end of the day, you'll still slave away for us rich people!" Enraged, I rushed over and demanded Bianca for answers.

If even one target’s Love Score or bond score reached 100%, I could wake up in my real world. But I failed all four. Because every target I tried to reach eventually turned toward Sophia Lane, the heroine of this world. They called my pain a performance. They called my tears manipulation.
