The main character in this anime responds quickly to what the heroines do. He has qualities that feel real, like most high school boys in the real world. This is also a very important point in romantic anime because almost all romantic anime with a high school concept show the character of the protagonist, which feels strange and not very real. And what needs to be emphasized is that what he is getting now is a gift because of his sad past with many rejections. Don't forget that the heroine characters in this anime are also fun and feel natural in their personalities without forcing it in their presentation.
So far, I really enjoy this anime; it's full of comedy, and of course, the harem theme really feels real. When I was in high school, I was popular among girls and dated all of them, and they were all popular girls too, although not as extreme as Rentaro compared to my previous situation.
My point is that I highly recommend watching this anime if you are looking for a good harem romance anime. I can guarantee you will not be disappointed.
