The tweets you posted also mention that one oc the intentions of this manga is to show Sasha in a wholesome relationship in spite of her impure background. The fact that Shu loves her and cares for her despite her not being a virgin and how he sees her beyond a sexual outlet is a key aspect of their relationship.

However I must wonder what were people expecting considering the origin of Sasha.

Not only did this author decide to reuse "Sasha", a character he constantly uses in his hentai manga (Ugly Bastard, GangBang etc..) He even has drawn an NTR version featuring the main character of this series getting cuckolded.

Not only that, but even in this "Vanilla" version he decided to also make it canon that Sasha isn't a virgin. This is just messed up and completely spoils any attempt at this series being wholesome or worth reading.

Proof directly from the author's mouth of her being a "non-virgin" in this "wholesome vanilla" version of the series despite still being a child.

This is like the most unashamed, unapologetic degenerate lolicon series to exist, not to mention how the character has a... past. It's crazy to me that Kadokawa serialized and published this lmfao, I guess that tells a whole lot.

But like... how did they get away with this? So out in the open? It's weird lol

Hmmmmm, she's finally not in an 18+ manga 😉

This isn't the first series she's been in
