Neiko knows that, despite how she loves oto-kun so much, she can't kiss him. Kissing is an expression of love. If they kiss, they can never go back, everything will change, and Neiko, isn't quite ready to risk their peaceful, happy sibling love, and a half-hearted kiss won't make things better. People don't get to choose who they love, and Neiko is not only smart, but also courageous to not be too frisky, and take things slowly, and let things develop naturally. Thanks for that failed kisscest btw author 0/10 dropped ktnxbye
