Hak-su goes on three blind dates. Ji-goo, an origami YouTuber, constantly offers to drink, Ji-yeon, a yoga teacher, is too energetic, and So-hee, a scriptwriter, works even on a date. These women are unbearable drinkers...

Director Kang annoys So-hee again. And Ji-goo gets upset by the bad comment from a kid during her YouTube broadcast. Who consoles me when I am painful? A drink.

The three drinkers faced a crisis. Turning thirty, they can't drink as much as they used to. Since they can't give up drinking, they come up with all sorts of tricks.

After drunken So-hee kissing director Kang, it turns out that something was going on between director Kang and the intern So-hyun. And So-hyun who saw their kiss threats So-hee. Thus, So-hee has a drink with So-hyun to solve the misconception but gets annoyed by So-hyun's attitude. And they end up competing their limit.

Ji-goo and Ji-yeon who were drinking at the sushi restaurant ended up in the police station fighting. So-hee came to solve the problem after work, but it is not as easy as she thought. Will their friendship be okay?

So-hee, Ji-yeon, and Ji-goo used to have ordinary jobs. Each of them was a publishing company employee, a nutritionist, and a high school teacher. What were they like seven years ago?
