Snapchat streak?

A guy always sends me a snap first, continues sending snaps even when I don't snap back. And when I let the streak die 4 times, he restores the streak 4 times and continues sending snaps. Just 1 snap a day though and nothing too private or personal, and we don't talk that much. Does this mean anything? Why does this guy keep doing this?
