This is one of the few live-action films that I've watched where I have yet to read the manga and I guess I was expecting a lot since I wanted to be surprised...to say the least. But really the reason why I wanted to watch this is because of the main actors: Yamapi and Nana Komatsu. I've seen Yamapi in his latest drama, From 5 to 9 and I wanted to see his acting abilities. But just like his character in that drama, Yamapi feels like a #deadfisheye actor. (I read in a Psycho-Drama article, there's agood analysis of his acting in his other works there as well.) He is good-looking, yes. (And his character in that drama requires for him to have that type of acting but after seeing it here too...) And he has the charisma but his acting just doesn't feel real. Nana Komatsu on the other hand basically swept him under the rug. I've just seen her in The World of Kanako and she is amazing. Her character here is suppose to the one who puts on the ultimate poker face (which she is able to do really well by the way) and Yamapi is suppose to be the one to complement that character by contrasting with her, yet he probably chooses to have a poker face/deadfisheye battle with her. Plot wise, it's nothing new. Teacher-student relationships are common in anime and manga. Is it done right here? Well, I can't say for sure. I just think that there's not enough development and scene for the two to make their relationship and feelings believable or sincere. Yes, they have chemistry. But it just lacks the development for it to feel like it's done right. We also don't know why Komatsu's character is the way she is. And why Sensei chooses to give her private lessons. There are a lot of gaps here which is why I truly didn't have much of the *doki doki* feelings. Side note: Also technically, even if Komatsu's character is 18 years old (the legal age in most countries), you're considered an adult at 20 in Japan and they even have a ceremony for it.
