About How It Became a 2-on-2 Situation Because of My Childhood Friend When I Was About to Go to the Fireworks Festival ~I Was Also Hoping for a Chance, but I Didn't Think She Would Be So Forward~

One day, the protagonist Yui decides to go to a fireworks festival with four people, including Kana, her childhood friend and the person she has feelings for. However... on the day of the event, the usually serious Kana arrives late, and Hao gets separated and can't join them, making things absolutely terrible... Huh? Was it Kana's calculation all along that we ended up in pairs? Being told something like that right in my ear makes me so awkward... The afterword also includes behind-the-scenes stories from the main story. I would be extremely happy to receive bookmarks, comments, reviews, and ratings. I'll be jumping for joy.
