The episode begins with a child's baptism, where Mu-hee's aunt and uncle are present. Do Ra-mi, now in a flashy red coat, arrives as the baby's godmother. After the ceremony, she confidently introduces herself as Do Ra-mi and reveals that she knows what happened to Mu-hee's parents. She warns them not to interfere with Mu-hee's life, emphasizing that she views Mu-hee as a distinct individual.
Do Ra-mi then visits Ho-jin at his house, where he quickly senses something is amiss. She urges him not to accept Mu-hee's apology or let her pursue him in Italy, saying that Mu-hee is inconsiderate of others' feelings. Exasperated, Ho-jin declares that this is over, once and for all. He's confused when Do Ra-mi instructs him not to mention any of this to Mu-hee and even more bewildered when he realizes she slipped a pill into his glass of water, causing him to pass out.
In the morning, Ho-jin wakes up feeling disoriented about Mu-hee's behavior. Yong-u arrives with his belongings and informs Ho-jin that Mu-hee is at her pilates class. Ho-jin attempts to find an interpreter to replace him for the Italy leg of the show and connects with someone named Yoko through his friend. His friend also wonders if Ho-jin's grandfather, who worked in publishing, might have a connection to Mu-hee's family.
Yong-u meets with Ms. Cha, the reality show's writer, and some colleagues to discuss the upcoming Italy segment. Ms. Cha mentions that Hiro has a niece he's fond of.
Ji-seon, who hasn't arrived at work yet, messages Yong-u saying she wants to talk to him. Yong-u tells her to come upstairs but doesn't realize she's waiting outside his house, not the office. A flashback shows both of them going up to Yong-u's place the night before. In the present, when Ji-seon goes up to his house, a woman opens the door, and she misreads the situation.
Meanwhile, Ho-jin goes to see Mu-hee and finds a poem in the dress she wore the night before, which was torn from a book at Ho-jin's house. Ho-jin recognizes it but Mu-hee doesn't. She apologizes to Ho-jin for everything before heading off for an interview. Later, Mu-hee recalls how during her previous shoot, she felt helpless and closed her eyes tightly. When she woke up, she was in her bed at home, and the shoot was over. Do Ra-mi had done it for her.
Mu-hee and Hiro embark on a meal encounter, with their respective managers seated nearby. Mu-hee presents him with a gift for his niece and discovers that Hiro has embarked on learning Korean. She is questioned about the kiss, but Mu-hee firmly denies it ever occurred. In Japanese, Hiro laments that he realizes she didn't kiss him because she likes him, but he wanted to confirm it nonetheless.
Subsequently, Mu-hee ponders if it was Do Ra-mi who orchestrated the kiss. She approaches the mirror and closes her eyes. Do Ra-mi emerges just in time for Ho-jin to call Mu-hee and attempt to converse with her. Do Ra-mi abruptly ends the call and then approaches Hiro, whispering something in his ear. On her way back, Do Ra-mi retrieves her passport from Yong-u and announces her departure for Italy.
At the office, Yong-u and Ji-seon finally meet, and Yong-u confronts her. He asserts that he never engages in one-night stands and thought they were dating. When Ji-seon mentions the woman in his house, Yong-u reveals that he's moved and no longer resides there. Ji-seon feels embarrassed upon learning this.
While Do Ra-mi is savoring ice cream at an Italian shop, Ho-jin appears to confront her! He's finally realized that she's Mu-hee's alter ego. He attempts to delve into Mu-hee's dark past to comprehend why Do Ra-mi is doing this, but she remains tight-lipped. Ho-jin employs his fluent Italian to return Ra-mi's impulsive shopping, ensuring her credit card is locked and her phone battery is low.
Ho-jin inquires if Ra-mi will leave once Mu-hee is happy, and Ra-mi responds that she might. At her request, Ho-jin departs to fetch a coffee for her. We then skip to Mu-hee awakening and realizing she's in Italy. However, the man approaching her isn't Ho-jin; it's Hiro. It turns out that Ra-mi informed him she would await him in the clock square in Italy. Ho-jin emerges from the coffee shop and observes the two of them standing together.
