As for MC, here some people call him a midget, although he is taller than his mom and sister, compared to the goddess he certainly looks too small, but I would not call him a midget or shota. But it would be better if he was more athletic, mom and sister are in great shape (they both have abs!), and he is an ordinary guy who has neeever attended a gym, he does not look very much like a man with a harem, it would be nice if you give him a little more muscle to make him look more convincing, or he can build some muscle in the future, and it would be logical for the story, but it would have been better if he had been a jock from the very beginning. And it's strange that they didn't even hug him at the beginning, even though they hadn't seen him for so many years, the reunion passed as if he had always lived with them and just returned from the store, write as you want, but that just was too unrealistic
