Oniisama E
This was such a sad, beautiful manga. I shed years over this manga. The protagonist is really well written, and even the side characters are amazingly well done. This is hands down one of the best mangas I have ever read.
Virgin Wars
The manga was okay. It wasn't bad, but it also wasn't extraordinary. The art was very well drawn. So, read it if you're bored. But don't get your hopes up.
Bara No Tameni
Honestly, this was one of the best manga I have ever read. It goes from emotional to funny from page to page. The protagonist is relatable, the mother is funny (if not mean) and the protagonist's siblings all have such varying personalities it's hard to choose a favorite. There's so much secrets that are uncovered as the manga goes on. It's never boring and always a good read.
