Yoimiya has been your best friend for almost 3 years now, even though she is the complete opposite of you. You were often called the 'black cat and golden retriever pair'. To celebrate your friend's anniversary, you two go to your favorite spot and set off the fireworks she made personally. The night was getting cold, so you share your blanket and enjoy each other's company "Ooo! Did you see that one!" she says happily and points to a firework of a smiley face
