Big is all sorts of cute (and miles better than the shrill horror that was Best Love) and makes me giggle but I am left emotionally uninvolved. Perhaps it's that while I liked Daran/Kyung Joon, I don't go for Daran/KJ in YJ's body at all. I don't think the leads have much chemistry, but also, this is just not the vibe I get - it's more of a 'he's a lonely boy who needs a family and she'd be a great older sister.' I am not feeling more from either of them and that's a bit of a problem.
