I really like this one. The characters are pretty relatable. It's nice to see an accepting family and some friends for Yurika. Minamo is an interesting second lead, and it highlights some of the hardships of poverty.
There's a few interesting hooks into future plot threads at the moment in the story (chapter 21). First, it seems like something went very wrong in Yurika's past relationship, but we've only gotten hints as to what happened there. Also, both Yurika and the teacher have also asked Minamo if somebody hasn't been coming to class recently. Tsubame is more than a little obsessed with Tsukie, and the story implies that she has some psychological issues (showing a thrice daily prescription during the obsession narration). Lastly, of course, there seems to be signals (blushing, heart flutter thoughts, etc) of a brewing romance between the two leads. This is most obvious on Yurika's end, and she does seem consciously aware of it (while Minamo is not).
