Assuming all the drama and hooking up is long done.
Which will never happen.
'sniffles'
Inoue's hair was oilier than usual.
Tatsuki-chan had been the first to notice. Of course.
One day, after karate practice, when the last rays of sunshine were leaving their little town, her friend turned to her and asked curiously if she was using a new kind of shampoo since it looked shinier, sleeker and had less volume. Confused, Inoue had denied and then wondered what could have happened to it. The answer to her fussing was a slight shrug and the words:
"Ah well, maybe it's from the sunset or something."
It had been a weird day and everyone had acted weirdly, so she just passed it off as another weird thing, born in the dying sunlight. Plus, she forgot all about it a few seconds later when she met up with Ishida-kun
The next one was Chizuru. Another 'of course'.
Even after she'd shown her that she wouldn't turn to the left, even after Ishida-kun had had that absolutely unnecessary talk with her, the redhead continued to glomp her and generally showered her with affection. One day, as she was having a cuddling session with the object of her love, Chizuru exclaimed frantically:
"My my, hime-sama, but your hair is so oily! You should change your shampoo!" and had broken into a lengthy rant how she should take care of her hair and not let it get out of hand, as she had done apparently.
Thanks to Chizuru's loud voice, the news (seriously? Wasn't there anything more interesting than that?) quickly spread and everyone knew. Not that they care anyway, but still it puzzled Inoue why so much attention was given to her hair and its oiliness. Was there something wrong with that? She didn't know so the natural thing was to ask Ishida-kun.
One pretty day, after school, as the sun was setting, sending its red rays far in the distance, she went out of school faster than Ishida-kun and went up to the entrance, tapping her left foot on the ground impatiently.
Usually he was the first to get down and when she finally arrived, he'd be there, smiling, waiting for her so patiently. Remembering him so calm and content just to see her face made her try to be calmer, more patient as she waited for him.
Eventually though, when he came out of the building, she couldn't contain her excitement and ran up to him for a hug. He chuckled as they connected, and lifted a hand up to pat her on the head, then he slowly threaded his fingers through her long locks.
After a second of a mushy reunion, he silently took her bag and swung it on his shoulders. They continued on like that, him with two bags and her ranting to him about her day. Story after story, she soon remembered what she'd wanted to ask him before.
"Hey, Ishida-kun when you were out of the classroom today, Chizuru-chan said my hair was oily. Is something wrong with it?" she looked up to him, big eyes and all and once again he found himself entranced by her image.
"Hmm, no, it's your same old hair," he answered and threaded his fingers through her hair once again.
