Of course, it has to be CB1 in reverse as both characters are reversed. Dev is the one who is obligated, Radhika is the one chasing him, he is the one rejecting her and emotionally blackmailing her to marry Rohan, Kanha making sure that haldi and whatever rasam happens with Dev. The only remaining would be Dev in Sehra marrying Radhika without Radhika knowing about it and Dev preparing the marriage bed for Rohan and Radhika and stopping them at the last minute.
Hmmm.... I do see a big difference between CB1 and CB2.
