nagataro never physically abuse him , never break his stuff , never insult him in anything beside his cringy phase , doesn't like him so she does have no obligation to be sweet to him, she is a bad girl and she knew it
the mc isn't so innocent or naive as this girl here he have been shown to be capable to trick her and manipulate her into humiliating situations , get her erotic sketch
also the moisture thing mean he used her as a towel also no one said the thing that made his hand moisted is water it could be as well something dirty
also even if it's not dirty he isn't close enough to do it since he isn't even her friend but a mere classmate and even then it would be mean
