Anyone know what manga this is? http://www.mangago.zone/read-manga/waka_to_banken/mf/v01...

I also just found this, and was wondering where it is from.

sorry to disappoint you but this is not a manga, it is an illustration of a BL novel, here's the link: http://www.amazon.co.jp/%E5%9F%B7%E6%84%9B%E3%81%AE%E6%A5%94-%E3%83%AA%E3%83%B3%E3%82%AF%E3%82%B9%E3%83%AD%E3%83%9E%E3%83%B3%E3%82%B9-%E5%AE%AE%E6%9C%AC-%E3%82%8C%E3%82%93/dp/4344830903
