They're twin so it's normal i think
You're not alone but I'm positive it's because they're twins hahaha (▰˘◡˘▰)
My hubby is an identical twin. And they are like that (well he and his brother) they think and sync together without even needing to discuss it. They were each others everything you can say. When it came to girls aswell. They handled each others for them without needing to ask. And always thought of themselves one. Eachothers. But not in a romantic way. Though totally connected and experimented in that way too lol It was weird for me but now totally normal
Ohhhh okay... Could to see that they have good relationship then
Is it weird that I'm getting a strange vibe between Aki and Shima. I mean I know their brothers but I can't help but feel that...
╮(￣▽￣)╭ Oh well haha
