Honestly I like this a lot, its nice to have the girl mesmerized, often its just the guy in most stories. The guy has a reason to not accept her feelings which is I knew her when she was a kid, its weird. The guy is attractive in that he is a trustworthy person, who is good with kids. Also we don't see tall power couples in manga, usually if the girl is tall its tall for a Japanese woman and/or the guy is a total manlet. The girl here is just plain tall being 192 cm or in Freedom units 6 feet and 3.5 inches, the guy is 185 cm in Freedom units 6 feet and 0.8 just shy of being 6 foot 1.
