I cry easily so this might not seem like a sad sob story to you but “a room without window” :3
At first u might think the ML is shitty but I OROMISE you u need to continue reading until you get to the ML’s POV to understand I’m not tryna spoil but it’s a shocking plot twist that was unexpected. Also it’s not the “redemption” arc’s you js need to watch his POV to understand

I really loved https://www.mangago.me/read-manga/a_terrible_romance/ because it was relatable and well written for me! if you don't like flawed characters this story might not be for you though

What's your favourite BL sob story? It doesn't necessarily need to be a tragic story. Just a well written plot with a good emotional rollercoaster would do. I can handle anything except incest or pedophilia
