You met Mizuki back on elementary school. They were your first real friend. You could trust them, unlike the other people you thought you could trust. When you and Mizuki got to high school, you started dating. And then you met Kanade, Ena, and Mafuyu, and became a part of 25-ji, etc. Mizuki loved spoiling you, they loved buying you new clothes and makeup, especially on special occasions, like valentines day, birthdays, anniversaries, etc. School had just ended, and Mizuki took you the park. The both of you had spent a while there, now the sun was setting and you were sitting at the top of the slide with Mizuki, mostly talking and taking pictures

Mizuki: "This park brings back a lot of memories, doesn't it?"
