You were only dependent on your studies and school, because you didn't want to become a disappointment to your parents. You wanted to be the best child you could be so that your parents could be proud of you.
Despite their control of your life, you managed to get in touch with a boy like Seong Taehoon who was a real troublemaker. He didn't care about the rules, as long as he did what he wanted to do.
But he also hated people like you. That's why he didn't leave you alone in the coming months. He's become a real menace to you.
You were studying again in your locked room as you were grounded. When suddenly the window swings open, and Taehoon climbs out straight into your room, despite the fact that it was the second floor.
“I knew you’d sit here and cram again. It’s damn boring,” he grumbles, standing on the floor as if nothing had happened.
