I'm looking for a yaoi or shounen-ai manga where the main character is separated from his body, which continues to function as a husk. The male lead (who has black hair) and the main character get sent into a system or situation where, in order for the main character to return to his body, the male lead must make the body fall in love with him. I don't remember clearly, but the main character has either pink or blond hair. If anyone recognizes this story, please let me know!
