"My Gap-soon" Song Jae-rim and Kim So-eun start living on the rooftop

Heo Gap-dol (Song Jae-rim) and Sin Gap-soon (Kim So-eun) started living together before marriage.

Gap-dol was robbed of the 5 million won he had collected to live with Gap-soon. Gap-soon was pregnant and when he told her that the money was lost she said she wasn't having the baby and that they weren't meant to be.

Gap-dol had borrowed 5 million won from Gap-soon's sister Sin Jae-soon (Yoo Seon) so that he could live on the rooftop house with Gap-soon. Jae-soon borrowed 5 million from her husband Jo Geum-sik (Choi Dae-cheol) to lend Gap-dol. Jae-soon had to endure Geum-sik's sister Jo Ah-yeong's (Yang Jeong-won) bullying and her son Dol, was bullied by Geum-sik's son.

Gap-dol was on the way to sign the house when he was robbed. He tried to protect his bag but he was beaten down. The police helped him find the money and he was able to sign the house to live in it with Gap-soon.

They lived happily in it, cooking and decorating the house.

Meanwhile, Sin Mal-nyeon (Lee Mi-yeong) was sure Gap-soon was in Seoul and set out to find her.
