I'm actually fine with sensei ending up with anyone. With that stealing bf girl, it'd be pretty refreshing to see them together since her kind of character isn't normally a protagonist (more like a support character). With kitashiro, she just loves him for so long and they get along really well. With the bookworm girl, she's so cute and straightforward, plus they both love books. Man, this is tough choice.
Anyway, I'm more curious about the sparkle. Is it actually not love? Idk.. It's either kitashiro's love not strong enough or she doesn't terribly want him, or sth else..

You brought up an interesting point here. Seems to me, those sparkles mean something else. I mean, how can one actually measure if someone's love is strong enough or not? Is there a measurement unit or something? And strong enough for what? And how does it manifest itself? I reckon, we all know such cases when someone shows off in order to make it seem like their so in love, however the primary motif is just to create an impression, and there's an alter motif underneath (the ultimate purpose, as to feel victorious over another girl by stealing someone else's boyfriend in Yadogiri's case). So the whole wording of someone's feeling being not strong/expressive/put an attribute enough, or manifesting in a wrong way, seems off (as if there's a manual about how to express their love in a correct and appropriate way, or like a very specific answer to a maths problem you can get only one way: by using a correct formula, duh). Although I must admit a lot of people tend to judge this way... So anyway, from my point of view, it seems that the sparkles indicate something else (e. g. high spirits, or competitiveness, or enjoying oneself, or anticipation etc), but hopefully we'll see.
HER?!?!? I saw that. I FUXKING SAW THAT.
