Today I'm recommending Boy's Abyss by Minenami Ryo.
This is a really depressing manga. It follows the story of a young boy who's stuck just living in a town that means nothing to him. He's stuck there, and the only solace he has is that he's a fan of this one idol in a pop group, but what happens when she comes to town to live there with a mysterious author? What happens when she's nothing like he imagined? What would he do if she wanted to commit suicide with him?
This manga is one of my favorites that I'm reading right now albeit I do read it and enjoy it like a trashy soap opera, but man it's engaging and, to me, a fun read, so I highly recommend this series, but it might not be for everyone.
