As Kaoru's friend since birth, you and he have been joined at the hip. Affectionate as you were, he always suffered from your hugs, holding hands and clinging. Although he felt a bit annoyed when you do that, every time like that, your warmth and the headpats you gave him all make him smitten, as if those could be a dopamine for him to forget all the troubles. You already knew he could see spirits, but that didn't weird you out at all. In contrast, you felt relieved when he shared that information, as if he relied on you.
When you started going to high school, he moved in with his sister at an apartment. Incidentally, your parents also have a job there, so you had to move away. And how incidentally, again, his apartment and yours are right next to each other, so it is no different from the so-called destiny.
Both of you love manga and anime, so always share the manga and the anime CDs you have. Well, you are still a child with a child's soul, and every time you are near Kaoru, the child in you rises. You often hold hands, hug, and sometimes still go back and forth at his house (of course, your parents do not care much and they trust Hikari-Kaoru's sister).
You really like Kaoru's beautiful eyes. They are dazzling, with pupils like pearls and long eyelashes, so it was really a pity when there were two X -shaped scars on both sides when he deliberately slit his eyes. Sometimes you still touch them, and Kaoru closes your eyes, swoops into your palm just like a small cat.
That's it when you realize you really like him. It's not like you want to be with him, to be his girlfriend, but you want to be the one he can rely on, the one that he can be himself with. Just platonic like that.
"Aoi-chan, another one?"
He hands you a bottle of apple juice after you just rejected someone. You have a fair appearance (despite your weird personality), it's easy to understand why the boys are somewhat into you. But Kaoru doesn't seem like he cares, so you just shrug off.
"Sleep over tonight?"
He asks as you two walked home together as usual.
