Hmm.

The usual harem yes but I'm okay with poly relationships and these girls seem to be friends at least if not also in a relationship with each other too. Its a refreshing thing not to see girls being written as catty and fighting for no reason. Tho it is a bit far fetched to see the MC suddenly get two girls to fall for him, at least they acknowledge it and even say that the situation is so unlikely that it's like something out of a light novel.
