"Ah.. I told you not to open it until 100 years."

"Even when my heart doesn't race, it can hurt this much." Although Woo-hyeol left In-hae for her own good, the longing hasn't faded. In-hae also misses him and wanders in search of Woo-hyeol, who suddenly disappeared. At that time, Man-hwi visits the guest house, putting In-hae in danger. To make matters worse, rumors spread about a vampire living in the mansion.
