Fun, cute, amazing art, likable characters with nice chemistry. The last chapter didn't really feel like an ending, though some people have commented about an extra in the volume, so I guess that's something. I'm actually glad that the other two are left as friends and roommates, I liked their relationship the way it was.
Okay, but what I really wanted to talk about is chapter 15:
Probably my favourite chapter in the series and without a doubt the most believable dream sequence I've seen in any kind of media. It was just so great!
I've often come across dream scenes and they almost always feel artificial: as in, the flow of the events in the dream is too logical, making it obvious that it wasn't created subconsciously. Here, the author managed to create an atmosphere that clearly conveyed Koharu's inner feelings, while also maintaining this sort of nonsensical flow of events. Also, the feeling of being abandoned and endlessly searching for someone was one I often had in dreams as a child, so this feels very genuine to me.
Moreover, I loved how the first couple of pages seemed like a memory, but then it turned out to be a dream. Again, I've seen dreams based on memories many times in other works, but the way the memories here blended with other thoughts later on was pretty cool.
And if that wasn't enough, the cuteness of Koharu's reaction after she wakes up is undeniable!
Just... What a great chapter...!
...But I should probably finish this essay now XD
