So awkward, so cute.
None of that. I've seen this exact situation happen before, in a Chinese or Korean manga. A girl confessed to her best friend at school, between classes, and gave her a little kiss. Her friend looked at her blankly, turned around and walked away without a word. The first girl, confused, followed her. They went back to class. The day went by and, when school was over, they returned to their respective homes. Never did the best friend utter a word in answer to the confession or the kiss.
The next day the first girl found that her bestie (now ex-bestie) had told everyone that she was a disgusting lesbo and everything was over between them. And the whole school started looking at her with loathing and avoiding her.
I expect Hinoka to be thinking by now that her future looks just like this story.
