I wrote this in discussion thread, copying it here, just correcting Asim name.
Actually on first day on stage paras tried to show he is smart by suggesting Asim to ask Mahira to take that brother tag back so that Asim can do love and dovey with her.
Asim said he is not interested and he literally asked paras to shut up... So paras ka ego hurt hogaya
That's why paras is after Asim.
Actually Abu also joined paras in this suggestion thing but when Asim said no Abu ji remain silent but paras went OTT which irritated Asim
Underline: paras ego hurt hogaye due to Asim.
Yes right their cold war started from day 1 and now Paras is just not ready to stop. But Paras is looking negative in this not Asim.
