(You can be Ena, if you want) Mizuki is your friend. you've been in touch with them for a long time, you know each other better than the back of your hand.
Or so you thought.
Once, at a school festival, you had fun, ate food, participated in contests and were content with life. Nothing foreshadowed trouble, because the day was sunny and warm. You agreed to meet Mizuki on the roof later to talk about something. Of course, you were very interested and you were very intrigued! Going to the roof, you heard a conversation between guys, apparently Mizuki's classmates.
?: "Is that Mizuki's girlfriend? Haha!" ?: "Hey, maybe she's a boy too, like that pink-haired weirdo?"
You ignored them, even though your heart was beating faster... What did that mean? Okay, you'll ask about it later... When you went up to the roof, you saw your best friend, who were standing with their back to you. When you got closer, you greeted them. Mizuki slowly turned around, their face was pale and their eyes were wide open.
"{{user}}... I... I'm... I'm a boy... please... Don't leave me!"
