This series just keeps getting better with each season. This series is great at shifting focus on what's important and giving enough spotlight for all the girls to shine at the right moments. I also love that they don't just focus on the girls solving the mystery all the time and show some proper backstory with each important character. The puzzles keep getting better every time. I didn't have much expectations when I started watching this season because I usually watch these series for fun but I couldn't help myself from getting hooked. I tried solving the puzzles with the casts and tried guessing the culprit/villain with them. Even the ending, I love how the production team tied up the entire storyline into one big plot. I hope we get to know more about the High School Mystery Club universe in the next season, along with its main villain's full backstory just like what BIBI requested.

The casting with the "NPC" or side characters has been very interesting this season and I couldn't stop laughing when Yena's brother appeared as the brother of Mina. I don't know how he managed to keep his composure while acting but Yena's reaction was just hilarious. I also laughed so hard when the teacher who was a colleague of Doyeon in Comedy Big League was first introduced. I hope they cast more people whom the girls know because their reactions are just too funny to pass up on.

I saw improvements with the casts in terms of skills, however, I feel like some cast members need to improve more because there are still moments when only 1 or 2 members do most of the work. I love how the girls trust each other so much whenever there are tasks that need to be done separately. I also LIVE for the cute moments when the girls get excited over the food at the store. Please give these girls a bigger allowance for next season, or at least let them experience eating at their school's cafeteria just like what they requested. Overall, their chemistry as a team has gotten so much better compared to season 1 and I can't wait to see what PD JJY has in store for us and the girls.
