Huh, I thought this would go for at least one more volume. I initially thought this was an ending that was planned from the start, and since the author was told it was the last volume they just went with it, but reading that note at the end, I guess they were happy to even get this far. At least that's how I understood it.
This was fluffy from the start, and it ended that way even though it had a harem-y setup and concluded without a harem ending. Sure, it wasn't anything absurdly special, but it was a comfy read and I can see myself going back to this in some time, just to smile.
While I usually hate the "everyone gets everyone happy ending" I liked all of the "main" girls and was worried one of them would get the short end of the stick, and even then, the ending wasn't that way at all. They got their feelings out and when it wasn't answered, they decided to slowly move on. It was an open ending for a lot of them, but with a big and clear sign of where it would go from that point on.
It was just a nice, warm read. Was it unique or stood out? Nah. But would I recommend it? Definitely.
