I feared at one point that it might just end as a close friendship like I've seen in a few Shoujo Ai. So glad that's not the case.

Like the header says it's pretty slow but extremely sweet from beginning to end. A little sad that it's over now and there won't be any more chapters of Hino teasing poor Koguma.

Hino and Koguma constantly engage in a kind of cute, always sensual, and at times quite sexy teasing roleplay.
There is no progress in the sense that they present themselves as a couple to the reader, but over time you do have a sense of them having become lovers.
From the start, Hino tricks Koguma into innocent sensual trade-offs that the latter gets embarrassed by. At the same time, you get the feeling that Koguma is sending a clear signal to Hino from the first chapter that she likes her, and rather than minding that she is being toyed with she wants Hino to go ever further in her lustful games.
The slight sensual exploits and the teasing are the main appeals of this manga and it does a great job at being sexy without showing much flesh.
The way Hino teases Koguma is extended to the reader and much of the comedy stems from the way she gets Koguma to give in to her request for a trade-off and the sometimes surprising ways in which the sensual play evolves.

This is funny and cute but it really goes nowhere after 50 chapters, which gets annoying as you might expect. That teasing trope is fine for a while but ultimately it means those mangas aren't as a good as they could be and drag on for too much.

By chapter 50 it should already have been completed honestly. There are yuri mangas with half the volumes and they're better.

Adorable shoujo ai manga. Simple story lines, not much action, meant to be a bit of a tease as the relationship progresses at a glacial pace. Ch 49 - so far they've done a few 'kinky' things but very shyly consider themselves friends and are embarrassed to hold hands. I'm going to keep reading, but I don't expect them to actually get together properly.
