Tell me, which one is Ravi which one is Baro?

Well, since I've listen to B1A4 song, Lonely and I wrote a fanfiction about Baro recently, I need to study about his character. Of course, Ravi and Baro is dfferent eventhough they are both rapper. hoho. 

Baro is more cute and lovely while Ravi is so active and talks a lot.

Well it just my opinion tho. If I was wrong, tell me :D

till then, XOXO :D
