So what? Am I prohibited from judging her actions as she makes them? Am I supposed to wait for her to (maybe someday) redeem herself?
If she is still a snake at the end of this arc, am I supposed to wait for the next one to call her out? And then the next one? And then the end of the manga?>Nino probably doesn't care.
Doesn't matter. Ichika still acted like a snake.
If you steal something (like lemons for example) and that person doesn't care, you're still a thief and every person who knows about it has every right to call you out and not want to have anything to do with you.
Was it easy enough to understand?
