I think they would make a nice couple. Their characters would go good together. Cat is a very airy, carefree, and fun-loving person. Beck is someone who wants to have fun and is very chill and relaxed. Cat would be his fun because of her personality. She would, in a way, 显示 him how to enjoy everything around him and to be silly without caring what anyone thinks of you. Sometimes it's the strange and weird pairing that makes the most sense. It would be fun to see how they would act toward eachother romantically and when hanging out. I think their personalities compliment eachother. To say they wouldn't last is ridiculous. I mean he lasted with Jade and she is a mean person and they argue a lot, so why can't he last with Cat? However, I do 爱情 Beck with Jade too. I think either Cat 或者 Jade would work great with Beck.
I don't want Bat to happen. Really, really, really! Only because I'm first and foremost a Cade 粉丝 and then I'm a Bade fan. Having that said, I actually think they'd make a very CUTE couple and they'd probably get along pretty well. The only reason I think they'd have a rough time is Cat is a little childish and hyper and Beck is really chilled and fairly mature.
