Ok, I been thinking about many stories.
The first one will be called “Got In Trouble” it’s where you’ll be in place after Daki and her brother were killed. But you were the one that got in trouble and has to do “something” for muzan to forgive you.
The second one will be called “Forgotten Twin” it’s where You, Yuichiro, and Muichiro are triplets. And you and muichiro forgot about each other, he’s the one that got his memory back before you. And yet you are basically the “odd one out” because you didn’t carry the teal ish eye colour nor the teal tips. You looked a lot like your dad.
