Listen, we're probably ridiculously invested in Meredith and Derek's relationship because of how unrealistically dramatic it can be sometimes. It's too hard to keep count of how many times Derek has pulled off a romantic gesture and harder to keep track of how many times he's thrown Meredith the signature Derek smolder. But sometimes the quiet moments between them are the most special, like their understated wedding vows.
