The author, who has been a girl three times, traveled to the world of tutoring and became Tsuna's brother. Wait, why did he change his gender! Well, don't worry about the details, it's great for me as the protagonist! Long live Tsunayoshi, of course I will not monopolize Tsunayoshi, of course I will help Tsunayoshi collect CP! (I prefer dark sandwich~ But for everyone, of course I have to put aside my selfishness and write all27 for everyone! Of course there will be dark sandwich and the like.)
