Yoo Ji Hyuk and Kang Ji Won get to know each other better by sharing personal stories. However, Ji Won mistakenly thinks Ji Hyuk is in a relationship with Yoo Hee Yeon (Choi Gyu Ri) when she sees them together. But later, she discovers that they are actually siblings.
There’s a real reason behind Ji Hyuk’s constant involvement in Kang Ji Won’s life. In his previous life, he learns about the affair between Park Min Hwan (Lee Yi Kyung) and Jung Soo Min (Song Ha Yoon) at Ji Won’s funeral. There, he witnesses her classmates engaging in toxic gossip and learns about the truth related to Baek Eun Ho (Lee Gi Kwang). Ji Hyuk then dies in a sudden accident and gets to go back 10 years. That’s why he secretly helps Ji Won get revenge on Soo Min.
Meanwhile, Soo Min’s friends eventually discover her true colors at a school reunion event. As her friends turn their back on her, she goes to see Ji Won and stumbles upon Min Hwan there. Later in the episode, Min Hwan is seen overwhelmed with happiness by Soo Min’s words of gratitude for staying with her. With the two sparking a romantic atmosphere, curiosity arises about whether they will end up together as Ji Won wishes.
