I've got one! 10 dramas/movies that gave you major SLS (second lead syndrome)
My picks:
1. Lost Romance watched so many Simon Lian works afterwards to try to make up for this.. while Happy Enemy was cute, it was WAY TOO slow burn
2. Memory of Encaustic Tile sorry folks, just not that big of a Lin Yi fan
3. Unique Lady although I love Gong Jun to pieces, I feel for Alen Fang who is ALWAYS relegated to SML :(
