The morning after Ji-ho kissed a total stranger, she wakes up to find out that her new housemate whom she thought was a woman is actually a man. Rather than the fact that they kissed, Ji-ho and Se-hee are sad that they can’t live under the same roof as they are opposite genders.

When Ji-ho gets proposed by Se-hee, she becomes confused as she doesn’t know what his intentions are. Sang-goo reunites with Soo-ji, but Soo-ji has no recollection of what happened before.

Se-hee and Ji-ho decide to get married, so naturally, Ji-ho introduces her boyfriend to her family. Se-hee must impress Ji-ho’s patriarchal father in order to get his approval. Meanwhile, Won-seok tries to make up with Ho-rang by getting her the sofa she wanted.

Ji-ho and Se-hee’s parents meet each other for the first time. Although Ji-ho and Se-hee agreed on not holding a wedding, Ji-ho’s mom and Se-hee’s dad think otherwise. Won-seok still can’t understand why Ho-rang got mad.

After the wedding, Ji-ho feels like she and Se-hee have gotten closer. Won-seok and Ho-rang run into each other at the wedding. Meanwhile, Sang-goo gives Soo-ji a piece of his mind when he sees her being mistreated.

Bok-nam helps Ji-ho get a job at the café he works at. Even though Ji-ho tells him that she’s married, he keeps coming onto her. When Se-hee sees the two together, he becomes jealous without even realizing. Meanwhile, Ho-rang comes up with a plan to make Won-seok husband material.

When Se-hee learns about how Bok-nam got reported on the dating app, he looks into it with great interest without letting Ji-ho know. Sang-goo visits Soo-ji at a café near her office, but she acts cold towards him. Unaware of Bok-nam’s intentions, Ji-ho agrees to drink beer with him.

Se-hee saves Ji-ho from Bok-nam. When the two get back home together, they have an honest talk. Ji-ho, Soo-ji, and Ho-rang go to a get-together between school friends.

Ji-ho starts developing feelings toward Se-hee and feels happiness from being able to see him every day. However, it does not last long as Se-hee’s mother pays a surprise visit. Meanwhile, Sang-goo cannot resist Soo-ji.
