Yaoi title

I'm looking for a yaoi story, I'm not sure but maybe this is just from a collection of short stories.

It kinda ventures the supernatural genre. Story goes like.. the uke and seme live in separate dimensions. People from the seme's dimension cannot live in the other dimension because their body isn't suited. The uke kinda has a weak body, because the truth is, he's a halfie. His father was from the other dimension. His mother died giving birth to him, after which his father returned to the other dimension and died there. A magical forest separates the dimensions.

Tried to narrow down my search within the yaoi + supernatural genre but can't find it. Need to recheck again. Hope somebody can help. ╥﹏╥

Thanks in advance.
