The white part of the room could symbolize innocence or goodness. For example, if it's a story about a person's moral journey, the white room might be where the person's positive thoughts and actions originate. The black part might signify mystery or danger. It could be where the person faces their fears or the source of evil in the story.
I'm not sure which specific 'white and black room story' you are referring to. There could be various stories with this setting. It could be a story about a person trapped in a room that is half white and half black, experiencing different emotions or events in each part.
In 'A Room for Two' manga, the story follows the daily experiences and relationships that evolve within the shared room. It's full of emotions, humor, and surprises.
