Firstly i also thought that vir will once understand ritu's love! But i saw the last episode: ragini & vir 사랑 each other & Ritu & Aryan 사랑 each other. so,they are happy with thier partners. Hence,vir can't never understand that ritu really realy loves her !!!!!!
i think it might be possible because 사랑 is that motion that never be hidden and in 프렌즈 it is impossible for example in this show only ragni do not want to tell his 프렌즈 that susmita juneja is her mother but truth can"t be hidden
