Firstly i also thought that vir will once understand ritu's love! But i saw the last episode: ragini & vir Liebe each other & Ritu & Aryan Liebe 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 Liebe is that motion that never be hidden and in Friends it is impossible for example in this Zeigen only ragni do not want to tell his Friends that susmita juneja is her mother but truth can"t be hidden
