This story was definitely something. To be honest, in comparison to Lily of the Valley, this one was way better. I'm glad that the professor ended up getting expelled it was definitely the better ending, and I was rooting for Yujin either way. I also loved Yujin's character it was really entertaining to see her different sides and how quickly she switched moods. I especially enjoyed how Yujin exposed the teacher that was so satisfying.
Now, onto the actual story. I wish there had been more to it, as in more chapters. It felt like it ended way too quickly. It would have been better if it had been dragged out like Bad Thinking Diary. Everything happened way too quickly, and you couldn’t really take in what was happening. Suddenly, Yujin joins Seonmin's school, and she already exposed the teacher within three days it was way too fast. The relationship between the characters couldn’t have been developed properly since each chapter was just pure sex.
But now, onto my next point: there was just too much sex. Because the story itself was short, it felt like Seonmin was a sex obsessed character. I just wish we could have seen more of her life outside of the sex, or maybe a date between her and Yujin. Also, what happened to a simple "hello"? The first chapter dives directly into Seonmin’s nudes. I know the author’s stories are usually like this, but it was still pretty funny.
Seeing how the teacher and Yujin were a bit two-faced, I wish that Seonmin could have been more like that as well. She seems a bit too submissive like, girl, stand your ground! How are you going to let a freshman toy with you like that? But at least there was evident improvement in comparison to Lily of the Valley. Between those two, I liked this one a bit more, so I'm glad to see Rangrari finally improving. I would still recommend that she hire a writer, though. The art was very pretty, as always I really like her art style.
Overall, this story was okay. It had its flaws, but it was readable. I just wish there were more chapters. 3/5.
