Jeankasa is really cute... I think they are like a fine example of a marriage relationship (if they ever get married). I also love Jean's attitude toward Mikasa. Jean is blunt and not introverted, and he often speaks or acts what he wants. But still, when he realizes Mikasa loves Eren, he chooses to love and protect her silently without disturbing her. I hope all boys can learn this attitude: first respect, then love.
