From Lezhin:
A study group is where students gather together with the same goal in mind and help each other succeed. But not every study group is the same. And nooobody said there had to be a single goal in mind. Sunggi enters a study group that is supposedly focused on studying for the government service exam. But that doesn't mean that's all they have to do, right?

Season 1 starts off with a great life right? But then season 3, is where that preview of Season 1. Guess what? He's "happy", right? But he's bored so he fucks plenty of other women on the side. And then guess what's next? She's also bored and goes back to being abused by her ex while still dating MC. I'm pretty sure they both don't give a fuck about hurting one another, so I don't why you would continue reading. Read series like Perfect Half or Lilith Cord. It actually has likable characters, interesting plot, and plenty of hot characters having hot sex. Don't read this shit.

Read this through chapter 25 and gave up.

Good art and sexy girls, but the story is basically a bunch of rotten people doing rotten things to each other.

I stuck it out for 25 chapters hoping for some growth and improvements in the two main characters and for some progress in their relationship, but all the story did was go around in circles without ever getting anywhere.

The main reason I dropped the series is because of the mc. The series starts off by the mc introducing an attractive women named Ha-Yeoung has his girlfriend. However, the story goes back before the couple met and shows that Ha-Yeoung his actually a promiscuous girl. Just like one saying goes, "why do you want to turn a ho into a housewife?' He met her through a sex study group, not too long from that they were fooling around at her apartment where here few days old ex showed up. The mc hid in a closet, while the ex started performing oral sex on her while the mc was watching through a crack in the closet. This chick could had at least waited until the mc left. Apparently she got back with him soon after that. This whole time, the mc had another girl that was willing to teach how to please a women in bed, but he is going to end up with the super slut?
