(as defined by: Two unrelated people of the opposite sex doing anything together outdoors shall always immediately be considered a date by onlookers, and pointed out excitedly by anyone that knows the two, as well as obtrusive demands like "So what exactly is the relationship between you two?", as if that's anyone's business.)
That said, since they're NOT actually dating, his little move to block the view of her bra strap (oh, the lewdness!) from the boys behind her is just white knighting.
She didn't bully him once this chapter. Some light teasing, but the fact that senpai can walk home with her without dropping his spaghetti and even deal with her shirt being translucent is a huge step up for him.
@LysandersTreason Does it even count as whiteknighting when the girl isn't even aware of it? I thought the whole point of that was showing off to a girl in hopes that she would fall in love with you or some stupid thing like that.
It seems to me he just didn't want other guys to oogle the girl he has feelings for (even if he isn't even aware of it).
