I thought those were paintings of Kyou, but her reaction doesnt seem like it is? Maybe the author just has a specific type of female face he likes and they all look the same?
I feel like the author just wanted to write a story about cooking with a new family after dude was lonely for years, and just picked a really questionable setup to do it
That's just not true man I went back and looked, and compared to the ridiculous chest in page 3 here?? There's nothing close to that in the early chapters
