I'm left to wonder what happened yet again

Yes, but there's no guarantee the sensei will accept her though the sensei likes girls too

I don't think she really expects the sensei to accept her, and she seems to accept that. It's more a desire to express herself than anything I think.

Did anyone else feel like they were going back and forward throughout this entire one shot?

sad.... sigh.

...im left wondering what happened in this chap.

The beauty of her feelings, the courage and decision to express them.
It's a nice little one shot.

the girl on page 19 reminded me of Ah-chan from Ali Hanna

I like how her feelings are portrayed. And how she deals with them. it's a bit melancholic, but there's beauty in it.
