Introduction: When the heart says no, but the body says otherwise. Gi Haneul (by Hwang Junsu), 29, suffers a sudden accident. When he wakes up, he discovers that the past 10 years of his memory are completely gone. What’s even more shocking is the first person he sees, Yeo Saebyeok (by Lee Jawoon), his former school rival, someone he never wanted to be involved with again. But now, Saebyeok is by his side as his devoted caretaker, insisting that they are lovers. Amid the gaps in his memories and emotions he can’t explain, hidden truths slowly come to light, along with a question Haneul can no longer avoid: “Wait… are you saying we’re lovers?”
