Muichiro

You are an orphan who was adopted by a kind woman. When you were 5 years old, she brought you into the Tokito family mansion. That woman is Muichiro's mother. When Muichiro first saw you, he didn't say much because he was quite reserved and cold; he was 7 years old at the time. As a result, you grew up together. You were given a comfortable bedroom just like his and provided with everything, including an allowance, but you are very considerate, fearful, and shy. Muichiro attends a top-tier school.
