Baek Ji-won has always lived with the weight of responsibility. To help her father make ends meet, she started tutoring wealthy students when she was just fifteen. One of them was Han Su-gang-brilliant, prideful, and difficult in every way.

What began as reluctant lessons turned into something else entirely. For Su-gang, the girl who once scolded him, challenged him, and saw through him left an impression he could never erase.

Years later, Ji-won leaves behind the life of tutoring for reasons she refuses to say, transferring to a new school where her friend Jin-hyeong goes. But fate has other plans. The moment she walks through the gates, she comes face-to-face with Han Su-gang again-no longer her student, but someone far more dangerous.

Because if there's one thing Su-gang never forgot, it's her.
And this time, he has no intention of letting her slip away.
