Alright, so I actually like this a lot. Not because I think it's a great work of deep art or anything, but because it's comfy, it's easy/quick to read, and it's something I find myself reaching for when I don't feel like reading heavier manga.
The art is fantastic, which helps. The shippy moments are cute. The characters are wholesome. There's not a lot of conflict in this, and I guess to some people it could be kind of boring. But I think it's perfect. Sometimes you just want to lay back and relax and read some really simple cute manga that's nice to look at. Shikimori is that.
