Hello, My Twenties!

The last of five to join the Belle Epoque shared residence, timid Eun-jae arrives in Seoul. She finds her housemates just as cold as the city itself.

House rules say men are forbidden to enter, but Ye-eun discovers men's underwear in their home. Conscience-stricken, she decides to hide it.

After discovering I-na's secret, Ye-eun declares that she cannot live in the same house as I-na. Meanwhile, I-na encounters a strange man at a bar.

On top of school, Jin-myung works day and night to sustain herself. She has no time for romance, but a guy from work keeps dropping hints.

In an effort to chase away the ghost in their house, the ladies of Belle Epoque decide to bring men in -- by hosting a house party.

The party isn't a huge success, but the housemates still make it memorable while uncovering some secrets but also leaving many questions unanswered.

Jin-myung gets excited when she finds her housemates waiting to pick her up from the airport, but for some reason, they don't seem happy to see her.

With their landlady pressing them to pick a new housemate soon, the Belle Epoque quartet has no other choice but to lower their standards ... a lot.

As Eun-jae and Ye-eun try to cope with the stresses of a new semester, Ji-won is still her usual perky self, but something keeps troubling her.

Returning home and finding a strange man in their bathroom, Ji-won, Ye-eun and Eun-jae panic, but it's Jo Eun who seems especially traumatized.

As Jo Eun struggles to define her friendship with Ye-ji, Eun-jae frantically searches for a way to undo the message she sent to Jong-yeol by accident.

Ye-eun teaches the housemates tricks to win over guys' hearts, which Ji-won uses on Sung-min to make him join her quest to recover her lost memories.
