It's sure a date by Japanese standards anyway
(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.
