I'm not really sure abt the first one, Arima shows his uhhh d*ck to the guy and said "there it is!" (≧∀≦)
It was in chapter 1 btw
Yes, i also think the second one is most likely. But who knows? :"
I know, but right now it's possible to go throw surgeries and put on some balls if you really want to, that's why I'm saying this theory as well
But as I said, this theory has barely a 1% chance to turn true
I think it might be something between tbe 2nd and the 3rd
No joke, I enjoy it a lot. But just like everyone, I'm just thinking of what is Arima's past. I do have a few ideas about his whole gender idea:
1. He is a trans, born as girl, but later on feeling like it's a "him" (though this theory is veeeeeeery weak even for me)
2. He was born a boy, but duo to certain circumstances, he was forced to act, dress and talk like a girl when he was very young, reason why he's so confuse right now (the last chapter - 3rd - makes it feel like this is very likely tbh)
3. He was born with both feminine and masculine attributes (at at least I once came across a manga where the lead was neither a he or a she, having both a dick and a chest, so why not, nature is very mysterious sometimes ╮(￣▽￣)╭)
