Man, this sensei is my favorite. her playfulness and attitude as well her indomitable will toward her goals are wonderful. Her smile at the end shows again why she is my favorite. But with the next arc being the other choice, I can't help but feel sort of sad. These kinds of endings where they are what if he chose this another girl shows a happy end for those two but then you remember the other girls and are reminded that in this route, they weren't chosen. A majority of people like their own girls and only want to see them win in harem manga/anime and i understand that it can be a weak way out if all the girls win and I also understand that realistically, one can only love one that way. (However, 100 girlfriends certainly shows us differently so who knows? maybe there are those who can truly love many at the same time.) With this, I'm just bringing up the point that I feel pity toward the girls because they loved the mc and weren't chosen but i feel kinda better when i think of it as fate. Many claim fate or destiny is written and we follow a certain path laid out for us but with love, it's what we make of it and for it to work, both must be willing to try.If the mc didn't try with the other girls, then it was not meant to be but then again, maybe in another lifetime or timeline, we'll never know.
