This fanlisting is for all forms of the relationship between Eichi and Mitsuki. From flashbacks, we see Eichi and Mitsuki together as children in the hospital. At first, it seemed like Eichi and Mitsuki has a big brother/little sister kind of relationship, but before Eichi left for America, he kissed Mitsuki and told her he loved her. Confused and emotional over this revelation, she ran away from him. He left before she could settle her thoughts tell him how she feels. She has not seen or talked to him since then.
