If you are someone who watches a drama without any external bias and are not affected by comments or social media then try this drama out. It started off with a really cheerful theme, with high potential, and had its fair share of angst and romance with some really really good music and dance sequences especially the OST "높이 (together)". As the episodes went by the main plot kind of was lost in the love triangle which more or less killed the vibe the earlier episodes created, well they recovered a bit around the last quarter of the show where there was some progress in the main plot but the impact was not that great. There were many obvious choices that would have actually made the drama much more engaging and not so frustrating until the last quarter but the writer I guess ignored all of them and messed up a really beautiful drama, which ended up being popular but could have been a lot lot better.
But even in that If you are someone who is looking to watch a good drama this is still a great choice as you won't have to wait a lot for the episodes rather they are all out and available for you, so you will feel a lot refreshing and might even enjoy the plot a lot. The actors did a really great job in their respective roles the portrayer of the personalities remained quite consistent and uniform.
Trust me as someone in this drama said "Sometimes it will feel like all the work is useless, but there comes a moment which makes you forget all of that." ?? You will surely like it just stick to the end.

Let's talk about the characters:
1. Do Hae Yi:- She is the kind of FL that you will surely start to like from the very start. She is responsible, caring, extremely funny, knows what she wants, and works for it. But we all know those qualities don't come easily as the price is the suffering they undergo to become like that. Her character was consistent in most parts of the show until a certain episode? which ended quite short? so don't worry. And had a really good and satisfying ending for her character really was soothing to the viewers.

2. Park Jung-woo:- Well my favorite character of the drama similar in a lot of sense to the FL, is also responsible, caring, not funny but a bit cute and geeky, and really the best captain which led Theia(the club) out from ruins to its formal glory. His only flaw is that he is way too protective of everyone especially the FL which kinda frustrated me?? yet gave me a lot to learn about how actual love is like where the safety, respect, and trust in the other person is way more important than the fact that they are with you. But don't get confused he still slayed It in every respect and things took a good turn for him. Well, our captain changed completely for all the good reasons towards the last quarter of the show so look forward to it.

3. Jin Sun Ho:- It's not that I don't like his character but?? I really had a lot of beef with how he did things in this drama. His role was the one that went through the most changes throughout the drama, at the start for all the bad reasons then things started going good towards the last quarter of the show. His background in the drama was most emphasized as compared to any character in the drama, but I wasn't able to sympathize with his flaws and problems because of how his action was in most of the drama. In terms of being a good guy for FL, he was also a really great choice but well the competition was fierce watch the drama to find out who wins. His ending was okay but they could have given him a better one??.

4. Tae Cho Hee:- She had a really small screen time but was really impactful. The badass vice-captain Theia???, the best friend of our Captain accompanied him in his plans to save the club and fought alongside him till the end. Her ending was also really satisfying and trust me she was a really really cool character who took a stand for herself and everyone whenever necessary. I wish shows would have given her more scenes.

5. As for other characters, I if keep on writing like this I might end up writing an essay on this drama so I should stop and keep it brief. All the other supporting characters like Joo Sun Ja, Kim Min Jae, Ki Woon Chan, Choi So Yoon/Choi Ji Yoon, Lee Ha Jin, Bae Young Woong, And the families of all the characters were so so good you will definitely like them a lot each character had their fair share of problems but were all fighting to solve them and be happy and then found it, each one of them ?.

There are multiple couples in the drama which really piqued my interest in club activities I guess I should find and join one too????. All the couples in this drama really feel natural and fitting, their complimentary personalities, their understanding of their partners, etc. I also looked forward to all of the club performances as that's where all the characters shined a lot, especially the FL and our always-highlighted Captain (that's where he really gave off most of the cool captain vibe ??).
Disclaimer: - This drama started a war between kdrama communities right from the very earlier episode which lasted most than 2-3 months ?? even I was a participant in that too.
