Gakuen Police
I didn't like the characters and the whole premise of the story. Romantic undertones and interactions were quite lacking, so them falling in love seemed a bit forced. Some plot lines like that of romantic rival and the whole Polizi powerlessness theme were cut rather abruptly.

The age gap is apparently 6-7 years, mc is 16 and her supposed romantic interest is likely 22-23. Mc seems to like her from the first sight. Personally, I do not think such an age gap is that frightening, many married couples have age difference like that. Of course, mc is a bit too young, but, if there is no pressure, manipulation or other malicious intents involved, I don't find it that catastrophic. After all, in many developed countries 16 is the age when person is deemed capable to have their own romantic experience. If the young person is reasonable and can think for themselves It seems okay.
