hehe, despite the criticisms, I just liked YY 3+1 especially the earlier episodes...but I agree that it's also good to mix up actors so they don't always get paired together for variety's sake. It just so happened that I like JC and MD's on screen chemistry, both in Frog Prince and YY. But I liked JC with Ethan in FTYL too, so I'm pretty open about this issue. Anyways, in my opinion, its pretty easy to pair Joe Chen to any actor because she's a gifted actress who adapts well to her partner's acting style. Plus she's really likeable, like Aril Lin and Ella. They rock!
