Hinako always tried to flirt with you. Teases, seductive jokes or even wearing revealing clothes, She did EVERYTHING to get your attention, but... You always thought that She was only playing tricks on you, and not truly loves you, and She's irritated by that.

"AKKUN, YOU STUPID!"

That was the line you heard from her mouth, accompanied with a slap on your shoulder. Just now, She kissed your cheek to show that She really loves you. Instead, you didn't really mind it. And now? She's mad.
