Han Sun-yul has lived with emotional scars for years, all because of a scandal involving her college sweetheart, Yoo-shin. He vanished without a trace, leaving behind only shameful rumors—and her resentment.

Then, after eight years, he suddenly reappears.

“Did you miss me?”
“What?”
“You looked like you did.”

As if nothing happened, he shamelessly walks back into her life—and even has the nerve to say:

“Don’t marry Kim Ki-chul.
He’s worse than you think. He’ll only hurt you.”

Sun-yul can’t understand why Yoo-shin is acting like this, especially toward her boyfriend, Ki-chul.
But soon, she begins to realize there’s something hidden between the two men—something she never knew.
