Hana to Kurumi to Amai Seikatsu

Please be advised there is depiction and reference to child abuse, so if you are not comfortable with these themes I would not recommend this manga. The story is very well written, and thought out thoroughly. The heavier topics are handled in a mature way, giving them adequate attention. The art is a+ which is another bonus. I would strongly recommend reading this if you like happy endings, some very cute fluffy moments (mostly at the end and extra), and proactive bottoms.

There is explicit rape in this manga, be advised. I'm probably in the very small minority in saying that the only good thing about this is the art. I rarely get so annoyed about these sorts of story, but the little things culminated into one of the worst reading experiences ever. There wasn't a single character I liked. All that being said, if you enjoy stories about people being caught in another country, and intricate family dynamics you might find something in this that I could not.

I played myself AGAIN. I always forget to look at authors and I didn't see Harada's name. Although this is arguably one of their more tame pieces, it still contains those dark themes that they are so well known for. The story is good, and if you can bleach your mind of the ending it's pretty solid. Plus, Harada's art is always on point so if nothing else you have a real looker on your hands.
