HELLO, MY TWENTIES!

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.

Money has always been a problem for Jin-myung, but when a promising job offer drops into her lap, she faces a difficult situation.

There seems to be a suspicious man lurking around Belle Epoque at night, and each of the housemates has a guess as to who it could be.

While her mom is out of the country on vacation, Eun-jae learns some disconcerting news involving her family members.

When a few of the housemates make some drastic life decisions, Ji-won is worried that it's all because of the lie she fabricated.

With Ye-eun missing, Jin-myung's mom in a legal mess and Eun-jae awaiting the autopsy results, Belle Epoque is just riddled with problems.

As the Belle Epoque housemates discover, some things are better left unsaid, some people never change and some problems just never get solved.
