Writing quality: I'd say it's pretty good, though it may be a bit unrefined and messy. The grammar is fine, with some occasional mistakes that get corrected almost immediately once pointed out.
Stability of updating: More often than not, the author updates 2 chapters a day. Sometimes, there's only one chapter, and rarely, there's no chapter at all. When that happens, the author tries to compensate in the future. Emphasis on "tries".
Story development: The story is kind of rushed but it's developing quite nicely. Uses clichés but I'd like to think the author uses it in a way that makes fun of or builds upon it, rather than just copying and pasting the cliché. Cons are that romance is kind of unrealistic, an indication that the author is inexperienced in that field.
Character design: I like the characters. There are some that are black-and-white but there are hints that they'll get fleshed out in the future. Also WARNING this is a harem, but the girls exhibit different personality traits and are unique from each other.
World background: This is the part where it's really just straight ripped off of other stories. Well, I can't say for certain since it's only in Chapter 39 and the world might get more interesting in the future, but so far it's bland and boring.
