Summary
Based on the April Fool’s 2025 event (or global’s future 2026 April Fool’s event).
When a powerful superhero called Funny Heart visited Saki in the hospital, that was when she knew she wanted to be a hero. Her wish was “to see them all again”.
Two years from then, fighting in the streets of Shibuya as Happy Heart, the apprentice of Funny Heart, Saki thinks that wish might never be fulfilled. But she’s not a part of HopeHope♡Heart because she’s a pessimist. She’s a part of the Hearts because she believes, and with Coda, anything is possible.

Summary
She didn't want to come back.
And yet, here she is - working in the pizzeria she swore not go back to.
She didn't thought herself capable of growing affection, especially to japanese groups, and after knowing them not for a long time.
Heck, she didn't even thought she would meet them in a first place.But she made a choice to, at very least, make their dream come true.
Perform at the stage.
She will do it, just for them...and for herself.
And, perhaps, finally deal with the conflict she had been avoiding for so long.
❗️Disclaimer❗️: This fanfiction will have a lot, and i mean A LOT of curse words, maybe some violence, and about nsfw and smut... Im not really sure. Maybe after the main arc lol.
All characters owned by their companies.
