As you guys know, I liked HeiShin. It's like one of my fav ships in Detective Conan and I would eat every single content media of HeiShin. But, I also like HeiZuha, although HeiZuha may not be my fav (But I still like it nonetheless) ship. Kazuha and Heiji friendship is quite dear to me.
I have this scenario in my head, where Kazuha did love Heiji, and Heiji also love Kazuha but not in the way that Kazuha would want him to. I imaging where Heiji already realizes his feelings for men but still in doubt about it. (because It's in the late 19's and homosexual is still out of the norm even outside of Japan)
He's scared to tell anyone, even his parents who always have his trust, but he had seen how people who had feelings like this were cast out, (He can't stand being alone) he loves his parents, but he doesn't know what's in their head, especially on how traditional they are.
I just imaging where Heiji and Kazuha have blowout and arguements. Kazuha doesn't understand, Heiji has said that he loves her yet, he couldn't accept it when she tried to loving him back (It's not particularly because Heiji had rejected her even though Heiji said he loved her first, It's more of a why wouldn't he wanted to be with her when he clearly loves her too)
This blowout had caused both of them to cry, questioning everything they had together, Kazuha's feelings, Heiji’s feelings and everything. This makes them not talk to eachother for months, untill Kazuha had enough.
She cornered Heiji, she asked, and beg him just to tell her, she swore that won't be mad, she won't be mad that Heiji’s with someone else or Heiji’s just not ready, she just couldn't stand them being apart like this anymore.
This time, there wasn't any screaming, or yelling, but it hurts them way more than it did a few months ago. Kazuha cries, still questioning because Heiji’s just wouldn't answer her, while Heiji is reluctant to tell her because he's more scared of losing her like this, than losing her before.
Kazuha was about to leave, left everything behind and never looked back, untill Heiji cries, he cries like the things that are holding him back is too much to bear, too scared to be judged and left just for his feelings. Kazuha can't just stand there, she comforts Heiji and cries by his side because not omce has Heiji ever breaks down, and right now he did all because of her.
After everything was calm down, both of their eyes were still red rims, Heiji had finally told her.
She realizes, oh how stupid and too much love that Heiji just had gives. Heiji told her about the feelings, the scared and the internalized homophobia he has, and how stupid she felt. It was clear as the sky yet she denied it every time in the past, no wonder Heiji was so scared.
It's true that Heiji loves her, but It's not the type of love that she had expected, but It's still loves too, Heiji loves so many things he gives his heart out, and not every loves is the same as people wanted him too, just like her when she realizes that.
Love is different from each loves
It hurts her that Heiji doesn't love her the way she wanted him to, but she's so grateful. It hurts more than a pierces sharp through her skin. But, she could change her love too.
To me, Heiji and Kazuha in friendship are more than a friend yet lesser than a lover.
