The first few pages are interesting: an isekai with a background character that ends up being the villainess love interest. But then he is pretty good at sword fighting even against adults, he is seven, he can spend 14h practicing all he wants, he is still 7 years old. It was also too quick how he already got close with the kid villainess, of course he being so handsome helped him in this part. Ultimately he is a background character with main character attributes, which takes the initial interest I had.
