Rohit and Ritu will obviously not let Akash and Shruti repeat their mistakes. Also Akash will not want Arushi to go thru what he went thru so he will surely apologize to Shruti. So how do you think Akash will apologize?
I think he will do it in his old style. He will go chori-chupke to Shruti's room and make up with her. Only this time there wont be any Kunal to chase him away. Maybe Aarushi will see him and shout 'Papa' and thus attract everyone's attention.
