Aryan doesn't know about Sandhir..right?

Randhir and Aryan had just met and they were glaring at each other. As far as I remember Aryan said everything he knew about Sanyukta in the 1st episode itself. And also when Aryan and Sanyukta brought up "handling relationships", it didn't look like he knows about Randhir.

aryan know abit abit randhir or maybe all bcz whn rd n sanyu met for first tym in irsc aryan have u met rd ? sanyu said yh jt now .
i dont think rd knw anything abt aryan expt he supprt sanyu alot

im loving alow thy show aryan n sanyu

I dont think aryan knows about sandhir... And if he doesnt then its a big blooper from cvs side ... He is a hacker , jisko sabka detail pata hai then how come not sandhir???
