purpose seems that to me is when shyam saw both arnav and khushi happy he became more eager to go to RM changing his own plan( making big dhamaka in RM) and i think because of his hurry the plan will get misfire and arhi will get more close
yup, jealous he was... he plans will fail till they get married im guessing... cause the CVs cant risk a successful Shyam plot if it will affect Arhi😆
