I'm on a short Manga kick right now, so at 21 chapters this was a good size for me at the time. There's a bit to discuss so I'll get right into it.

Story: so the actual plot itself is a really neat idea. The problem is the writing and decision making on behalf of the author. There's a lot of information, and plots that are all going at once, youre left feeling a bit flustered with the amount of things you have going on. I don't mind subplots, but with only 20 chapters you need to tone it down. Though the ending is own for a sequel, I'm not sure if I would read it with how jumbled this one went.

Art: really nothing special. I'm not sure if it was the quality of scans, but it made it seem rough or old.

Characters: to be honest half way through I was wondering if this was a harem series. Cause close to the end it was shaping up to be that way lol. Maybe that's why it has an adult tag on websites? Idk. But the characters are pretty basic.

I'm the end I wouldn't recommend this Manga. It's nothing special, and the ending is disappointing. You expect something bigger and you're short changed.
