What's the title, please ? (2) (๑•ㅂ•)و✧

Hello ! It's me again ╮(￣▽￣)╭

So, as I've told you in the previous question, I have another manga title to ask you ┑(￣Д ￣)┍

Always in the "yaoi domain", this manga talk about two "gods"
I think they're the death and the life spirit...I don't remember ╥﹏╥

I remember, two of us may juste see each other few seconds, when the door of "Hell" opens.

One of them is dressed in white, and the other in black.
I think, they never really see them. Either, they can't pass the door.
But they can talk together through the door.

At a moment of the story, the "white god" can't take anymore and decide to pass away the door for find the "black god". But a part of his body turn into black. And because he don't want to see his love dead or other thing, the "black god" closes immediately the door.

Toward the end of the story, I think remember that the "black god" is in danger and the "white god" want to help him. He force the way and open the door for find and help. But I don't remember why, two of them exchange their places : thus, "black god" become white and white god become black (you understand ? (⊙…⊙ ))

So, that all that I remember（/TДT)/

Can you, please, tell me if you know this manga ? ヾ(☆▽☆)

thank you so much in advance for you help ヾ(❀╹◡╹)ﾉ~

See ya ! ٩(๑❛ᴗ❛๑)۶
