Yin Chaiya didn’t want Haena to get too close to Seowon, so she arranged for her to take Baoqian’s car.Haena ostensibly agreed to the arrangement, but Seo-won pointed out that Baoqian was often late, so he invited Haina to take his car instead and agreed to meet in the park.
Cui Yu expressed doubts about Shuyuan's driving skills because although he had a driver's license, he had never actually driven.But in order to be able to travel with Haina, Seowon improved his driving skills in advance.
After Yin Caiya learned that Haena did not plan to take Baoqian's car, she hurried to the park to find the two of them, which delayed their departure time.It was raining heavily at that time, and Shuyuan was driving in a hurry. Cui Yu called and accidentally revealed that Shuyuan could not actually drive. This made Haina very worried, and she held on to the seat belt tightly.
Fortunately, they finally arrived at their destination successfully. In order not to be late, Seowon took Haina's hand and rushed to the wedding venue.
At the wedding, Hina was very envious when she saw her colleagues getting married in wedding dresses.Seo-won went on stage and sang a song to express his wishes for a happy wedding to them.His voice is full of masculine charm, which deeply attracts Hina and makes her start thinking about her wedding.
A colleague asked Shuyuan to help move things. After learning about it, Yin Caiya asked him to take her to the passenger terminal.Bao Qian deliberately calls Seo Won to taunt him and try to sabotage their plan.Seo-won took the wrong route due to a navigation error while driving, and the two were forced to return directly to Seoul.
Baoqian and Haina had a heart-to-heart talk at the beach and said some strange things.When the two left, Haina walked in front, and Baoqian talked to himself, recalling the scene of Haina's previous life.He seemed to see some of his past self.
As soon as Seo-won got home, he sent a message to Hae-na, apologizing for not being able to see her off in person.Yoona gave Haina an idea and asked her to ask Cui Yu for help.While Seo-won is sleeping, he puts Hina, who has turned into a puppy, into his bedroom.
After Cui Yu learned that Haina's transformation was a family curse, he became curious about the cause of the curse.But Yuze stopped him in time, but he still learned that Haina's transformation was due to her kiss with Shuyuan.He confirms this to Hina and agrees to help her in the hope that they can take this opportunity to develop.
At night, Cui Yu urged Shuyuan to go to bed several times, but Shuyuan could not fall asleep because of his busy work.Cui Yu thought of some ways to make him sleep.When he went downstairs, he found that Yoona had appeared with the transformed Hina.Yuze prepared all the tools, and the three of them immediately took action and put Hina, who had transformed into a puppy, into Shuyuan's bed.
Looking at the sleeping Seowon, Haina's heartbeat quickened.She thanks the curse for bringing the two closer and recalling some heart-warming moments.But when she thought that everything would be restored to its original state after the curse was lifted, she hesitated and kissed Shuyuan.However, the kiss did not turn Haina back into her human form but woke Seo-won up.
Seo-won screams when he sees the puppy, and Cui-yoo rushes in to comfort him and give Hae-na a chance to escape.Haena's curse has not been lifted, and Yoona suggests that she go find her mother and ask why.By looking through archives from the past, they uncover clues that may require the two of them to kiss at the same time to unravel the curse.
