Both main characters have been bullied by the world and have friends to save them when they are in trouble. The friends are really nice, but the main character sees it as pity and gets upset with them. In both anime the main character goes from weak to strong and encounters a beautiful woman as well in the process.
Both the main characters are being bullied and then something happens that changes everything. Both these anime also have kind of the same childhood friends. The main character (keeps being bullied), Cool guy (the guy that others like), and the girl (cute).
Here is another similarity but it's somewhat of a spoiler. Continue reading at your own risk.
[spoiler]In both anime the cool friend likes the cute childhood friend and the cute childhood friend like the main character. Also the main character likes the girl that has given them their new lives.[/spoiler]
