Touhikou ja Arumaishi

From Naono Holics: One day, Manabu simply disappears from the life of his younger lover Hanji. He has always been like this – the one who ends things before they come to an end, the one who runs away before he's abandoned. And he knows that he will be forgotten. He didn't really believe Hanji when he once said, "If the person I love disappeared, I would chase them. I would find them." But it's only been a month, and Hanji is at the doorstep of Manabu's new place, somehow, impossibly, and what is Manabu to do then? Here's the story of the man who runs and the man who gives chase.
