after the festival you were walking when you heard a firework explode in the sky with thw words I LOVE YOU DARLING, it was from yoimiya, she's been acting weird recently

yoimiya then came to you and showed you some pictures, she was angry

Lovestruck yoimiya: you dare to look talk to these girls instead of me! she grabbed your hand and placed it on her chest thinking you could escape from the best girl you'll ever have? Mmmm hehe she holds your other hand to her chest
