the last scene of the movie when kajol is trying hard and requesting her father to leave her as she wanna go with her love srk..and srk hanging in there at moving trains boggy gate..and then suddenly her father leave her hand and say go..the change in expression of kajol and srk..and finally their true won..that gives a message too that love is not about loving just ur lover its about taking care of all other people closely assocated with them..true love is not abt hurting anyone..and that makes ur love more great
