Synopsis

The blood on In-hae's lip triggers a memory in Woo-hyeol, reminding him of Hae-sun. Woo-hyul wonders if In-hae is the reincarnation of Hae-sun. In-hae is concerned about her first kiss with Woo-hyeol and feels more uncomfortable seeing him, who is employed as a janitor at the school she works at. Yang-nam tells Woo-hyeol that if he drinks In-hae's blood, filled with love, he can become human.
