NAt the end of the day, it's just a cute manga about a pair of siblings living in the capital while the brother sorts out his love life. Don't get me wrong, we have an elephant in the room; the manga is a slice-of-life, but it uses loli bait to attract its initial audience. The first and second chapters are more appealing However, the manga ends up focusing more on basic ecchi, panties, underwear, and occasional nudity, with nudity being more frequent among the older characters, However, it also exists in the lower strata of society, if you know what I mean. Ecchi is also limited to situational things, accidental views, misunderstandings; it doesn't fall into harassment or abuse. Regarding the protagonists' relationship, it is indeed a sibling relationship, but in an ecchi manga, he's not trying to take advantage of her, nor is he trying to take advantage of her, The relationship between the two, and between a guardian and his younger sister, is more comical than erotic, and the creature's nude photos evoke more astonishment than interest. Not to mention that the dynamic shifts from her following the "anime sister" script to her living life like a normal child, making friends her own age very quickly. Basically, this is just a manga with ecchi content, not a manga about ecchi. If you skip the first two chapters, the most frightening and problematic parts probably disappear, leaving only normal discomfort. Regarding ecchi in the lower classes of society, if you know what I mean. Regarding the manga's problems, it kind of avoids tackling the more complex issues it's designed to address. It comes close but then drops the ball and focuses on something else. No one ever considers her schooling; the other children go to school, but none of the adults question why she never goes, The issue of Christmas presents isn't being developed, not even as a joke. I thought presents would be a recurring theme, but they don't bring it up anymore, and in the end, He never explains to anyone that she was a gift, he's not confronted about it with his parents, the legal issue of it not being considered, it's not that the answer given is bad, They simply didn't want to think about it or develop it. But at the end of the day, the manga came out a 7.8, maybe a 6.8 if you take away more points for the juvenile ecchi content; the relationship between the characters is nice. The characters' drama is good, the tone was heavy-handed, but at least it didn't degenerate into incest; at the end of the day, it's a story about a brother who takes care of his sister and looks for a girlfriend When he gets one, the story ends and all the other loose ends remain open. It's not offensive, it's not 100% satisfying, but it's passable, simply not turning into an incest story That's already a reason to celebrate. I enjoyed reading it, the ecchi bothered me a little, but at the end of the day I don't regret reading it. It would be nice if the other aspects were developed more. Especially the craziness of Santa Claus giving relatives as presents; I'd love to see that escalate to its ultimate comedic consequences. The manga can be interpreted as a young adult living with an adopted sister, half-sister, or sister resulting from a marriage between one of the parents and another person.
