I just took a look at the LN cover again. While some of the outfits are better, and some character designs too, I do appreciate having an older MC. Even if it was against the intention of the author. I do prefer looking at handsome guys more than little brats, like at least they will be more proper you know. I do like brats too, but I prefer them to be unrestrained and overwhelming, like Lloyd from 7th prince. If he can't be allowed to be childishly OP, then just make him an adult to begin with, that will be more acceptable. I hate making a child MC then have him behave like the most mature adult ever, that just doesn't sit right with me. Children should not be shackled with all that pointless etiquette, they should be unrestrained and free to do whatever they want.
Yeah I like loli too, I ain't gonna hide it, even tho it might have been better for me to hide it I think I should just throw this out as well so whoever thinking about losing respect for me can lose it right away. I wouldn't want a cute loli to act all politely either. Like, imagine a loli maid, it would be cute to see her act politely, then suddenly an event happened which show her cute childish side, now that is good. Same goes for the shota.
