The ninth episode of "Romance in the House," titled "Back to the Mi-Rae,"
opens with a tender moment as Mi-rae prepares for her day, accompanied by
Tae-pyeong. Their budding romance is still in its honeymoon phase, and the
awkward small talk outside her villa is a testament to their nervous excitement.
However, the tranquility of their morning is short-lived as Mi-rae returns home
to find her mother, Ae-yeon, has changed the locks on their apartment.

Ae-yeon's decision is a clear message to her daughter: it's time for Mi-rae to stand on her own. The conversation outside the apartment is heart-wrenching, with Mi-rae visibly upset and Ae-yeon maintaining her composure for the sake of her daughter's independence. The moment Ae-yeon turns the corner, she finds Moo-jin waiting to provide comfort, encouraging her to let her emotions out.
The next morning, Mi-rae is inundated with messages, one of which is from Tae-pyeong. He has been encouraged by Mr. Nam to work as an intern for three months, a prospect that brings a mix of anxiety and anticipation. Meanwhile, Mi-rae seeks solace in physical activity, visiting the taekwondo studio to break boards and release her frustrations.
Ae-yeon, on the other hand, spends time with Moo-jin, who expresses his desire to be a better father to his children, something he failed to do in the past. However, their peaceful interlude is threatened when the landlord's daughter uncovers a connection between Dragon Investment and the former landlord, suspecting foul play. Her call to Jae-geol is a warning, and it sets the stage for potential conflict.
Jae-geol's pride is tested when he has a meal with Jeong-in, who offers to pay. His refusal is a display of his stubborn nature, and it adds another layer to his character. Mi-rae confronts Moo-jin about his intentions, seeking reassurance that he can be a constant source of happiness for her. Moo-jin's response is heartfelt, promising to do his best and acknowledging the family's resilience.
Despite her initial displeasure at being excluded from the decision-making process, Mi-rae seems to be coming around to the idea of independence. Ae-yeon, in a separate conversation with Tae-pyeong, is convinced of his good intentions towards Mi-rae, which eases her concerns. Moo-jin's paternal side is further explored when he tells Hyeon-jae that he needs to return to school and offers to pay his tuition. Hyeon-jae's confusion over his father's sudden wealth is left unresolved, as the landlord's daughter's investigation looms over the family.
The landlord's daughter's cryptic encounter with Mi-rae is filled with veiled threats and questions about Mi-rae's identity, hinting at a deeper mystery yet to be revealed. Ae-yeon's job search leads her to a part-time role at a salon, where her natural beauty and charm are immediately recognized.
Tae-pyeong's gesture of buying gifts for Mi-rae after work is a sweet moment in their blossoming relationship. However, Mi-rae's return to her messy home is a stark reminder of the responsibilities she's taken on. The cleaning process is daunting, and it gives her a newfound appreciation for Ae-yeon's efforts.
A letter from Ae-yeon, hidden among the boxes, offers advice and reassurance, highlighting the bond between mother and daughter. Mi-rae's eventual understanding of Ae-yeon's sacrifices leads to a heartfelt reunion, where they find solace in each other's company. Moo-jin's phone call seeking advice about "the woman" who knows everything adds a layer of intrigue, as he is told to handle the situation on his own. The episode concludes with Tae-pyeong's introduction as the new intern at work, with Mr. Nam's announcement that Mi-rae will be his mentor, setting the stage for potential complications in their professional and personal lives.
