1. in what chapter the anime ended please?
2. why is this labeled as SMUT?
i just noticed it had smut on the genre

Chapter 28 is the first chapter with new content compared to the anime. The reason its called smut is because they do show a bit of nipples, however that's only in the earlier chapters. After that, there really isn't any smutty content. I think it was originally going to be a lot more smutty, as the author tends to have more sexual content, as they generally write smutty one-shots. So if you're not into smut, don't worry. The most you'll see is a set of nipples in an earlier chapter with Aoi.
Soooooooooooooo short
