WHAT IS SO GREAT ABOUT THIS DRAMA:
I didn't know what to expect from this drama since I checked it out at first because I was a fan of the main leads and I love dramas with a few hot guys. But this drama has surprised me by being better than I ever imagined.
1. How the four main characters go through different trials and overcome obstacles, forming a close brotherhood (yes, even with the main girl lol) among themselves was heartwarming and fun to watch because we actually get to explore what their characters would do in different situations, and also get to connect and empathize with them.
2. It was hilarious to watch. I love the interactions between all of the characters - it is especially funny when the four of the main characters are together and make fun of each other. The teachers also make a great comedy group. I love that even if most of it is hilarious and had me laughing out loud many times like a crazy person, I also like the times when it becomes serious as we get closer to the truth of the whole mystery in the story. Every main character is well thought out and has a purpose and connection to the whole mysterious backstory of the plot.
3. I also like that this story shows that people can change even if they didn't start out as the best character because many times, that is what it is like in real life. The character development throughout is great, which I greatly appreciate because we also get to see changes in relationships among characters. Everyone in here has some kind of character development that makes sense, which is why I rate it so high, because this makes it interesting.

The two main characters:
---The thing I was mostly surprised about was how casual the main girl was even when she had somehow admitted into an academy full of men. In the beginning, she definitely had a problem dealing with living with men, but as the story progresses, she carries herself well, like a normal human being. I actually have a lot of problems with some cross-dressing dramas sometimes because the girl makes it soooooo obvious that she is a girl.... like, come on, people aren't actually this stupid. And this may be due to the scriptwriting, who knows. But the main actress here didn't do that, which I appreciate. IDK. it might be her acting, or the scriptwriting, or directing, but it just felt different and more natural, like how an actual person who is smart would act like. She also shows that she is a smart person, smarter than many of the men there even if she is a woman.
---This drama also made my heart flutter because I fricken love the male lead's character. Like, he is smart, caring, and strict, and hella good looking, but he is completely clueless about the opposite gender since he's always only focused on his studies. When he finally realizes that he loves the main girl, omg, it was cute and hilarious. He's just a character you can't help liking because he treats the main girl so well because he sees great potential in her and also willing to admit his mistakes.

WHAT I DISLIKED:
1. I was really looking forward to when the villain was finally caught and put in jail, dies, etc, whatever. This was supposed to have been the climax, but it really fell short, which made me REALLY disappointed. Like, everything just felt like a flop. Sigh. The whole drama was great overall, but the story revolved around trying to find the villain, yet it was just- ok, he got caught, that's it - type of feeling, making me feel empty inside.
2. Also, I wanted more romance between the main leads!!!!! I actually like that the love in here wasn't too complicated because it was more about friendship and equality. But still!!! I just wanted a little bit more and I would have been satisfied! I felt like the drama ended a bit too abruptly, with the epilogue not being long enough, which may have also contributed to the flop of the climax when the villain was finally caught.

Anyway, because of the reasons above, I rate this drama overall an 8.5.
