The first part of this review doesn't contain spoilers; the second does - read at your own discretion.

First part:

I think I went in with absolutely, utterly low expectations due to other reviews and I think that helped when it came to my enjoyment. Some of the things other reviewers talked about didn't take the spotlight during my own watching, but I must admit that I could be biased due to my love for shoujo manga and their adaptations in general. If you want to watch a movie which doesn't take itself too serious and talks about high school romance, this could be the movie for you. The leads did a pretty good job with the script they were given.

Second part:

I think a lot of people missed the point of this movie. They are both 17 years old and have no other experience in romance. Both are too afraid to speak out their feelings, but it's obvious to both of them they're in love with each other. FL's reason for not confessing was weak, but she's a teenage girl dreaming of being confessed to. ML's reasons for not confessing were much deeper - the feelings of insecurity and not being good enough.

Is it the most serious movie you'll ever watch? No, not by a longshot.
Is it as bad as others present it? I'd argue no.

Honestly, shoujo manga's are famous for their dramatic shenanigans and over-the-top events. It comes with the territory. And when I put into perspective myself at that age I kind of understand the impulse to do stupid things even when you know better - you're only 17. The whole point of growing up is making mistakes and having enough time to correct them, learn and develop. Which is something their characters managed to do by the end of this movie.

Second lead syndrome did hit kinda hard, though. Damn.
