I know there's loooooads of reviews for this show already but I-...I just to have say something. (If you're having a "tldr" moment, skip down two paragraphs!) I really liked this show. Seriously. Up until the last episode I was as hooked on it as I was with Healer, despite not knowing any of the actors, having not seen any of the other 'School' series, or even expecting that much from a school based drama. Yet it was still honestly fantastic. All of the acting was superb, especially the main actress! The music is so catchy that I have the main song, 'Reset', as my ringtone now. The story hooked me in and just wouldn't let me go: despite what other people seem to have been saying, I personally found it be the perfect balance between romance and suspense, and I watch RomComs all the time! And it wasn't anywhere near as predictable as most Kdramas either. But the ending...? I'm sorry. There will always be someone out there who will disagree, but I was not satisfied. I knooow. It's symbolic. It's deep. I can see why they did that. (And I won't say anything more than that because spoilers!) But...I felt so empty at the end, with this confused heart that really wished there was more to come but knew there wasn't. So personally, if I was writing the only review my past self could see, I'd tell her to watch it. It's brilliant. Even if the ending has got a bittersweet and only partially satisfying ending, it's well worth the time regardless.
