We r confused too even though we have been watching from day one .
Hope Anu17's post will help and rest watch and wait dear :)

1. Radhika and Dev became friend when they were young...Dev told RAdhika that his name is Kishan kannaiya because her name is RAdhika ...They played together and were enjoying each others company . Dev got his pants dirty and Radhika bought him to a ghat and he started cleaning his pants ...Randhika started splashing him and they were both having fun ...To tease Radhika Dev took her duppatta and started running ..RAdhika and Dev got married unknowingly because RAdhika was holding the edge of her duppatta and going around the fire together without realising what they were doing...A pandit saw them and tried shouting telling them to stop but they couldnt hear him ..So then the pandit went to then worroedly and RAdhika and Dev started running when she bumped into a man holding a sindoor plate ..It came on her forehead and they ran away before the pandit scram at them....After the pandit told Radhika parents that she is married to a boy //but Radhika doenst understand what happened....Dev leaves back to mathura with his family and the pandit tell RAdhika that she is married to the boy but its too late before she can tell her Kishan kanhaiya that they are married..

12 years later .....Radhika is still waiting for her Kishan kanahiya ..she doesn't know his name is Dev ....we dont know if Dev still remembers his childhood friend or not...

The bari Bahu wants a girl for the youngest grandson who is "Rohan" she wants a choti bahu that is manipulative . Dev and Radhika meet when they are grown up ...feel connected ..but Radhika and Dev dont know each others name yet ....Dev didnt know he had to bring shagun for the girl he loves and he is heart broken knwing that the girl that he love is chosen for Rohan ...RAdhika thinks that Dev is the groom when he came for the shagun ....And when her father found out about her Kishan kanhaiya he said its the youngest son of the Purohit ...Radhika is happy and thinks that she is going to marry Dev ....her KK....because she feel an attraction towards him and likes him too 😳

Radika thinks she is marrying Dev but she is picked to marry rohan ...
*** But a suspence is hidden ....Dev is the youngest grandson of the Purohit family but we will know when the time comes 😉
