By Far my favorite series there are 7 seasons so far. A great mix of relationships, drama, and medicine. Season 1-3 are more sex and relationship heavy, while seasons 5-7 are more medicine and moral dillemma driven. Expect the unexpected, gory scenes, fallouts, and changes in cast. You won't be able to help falling in love with Mc. Dreamy, hating Yang, but in the end you root for them all.
I can't wrap my head around it, Mac. You get up, you go to work, see the people that you know, you talk, you laugh. You're living your life, then suddenly, boom. It's just over. Just like that, and you never even saw it coming.
