As we all saw...when Manik asked them to cum at 7.30 n they were cmg up from the stairs...Mukti was annoyed n irritated when Aliya asked Y she is is behaving like that
In that scene Cabir noticed Dhrulya when Dhruv was putting something on Aliya's hair...n Mukti asked Aliya..."Y she is happy now a days"

Cabir noticing them can b my imagination but Mukti have some doubt now after yesterdays episode
Bcz she noticed Dhrulya in Canteen...if i m not wrong
So i think soon Dhrulya's relation/equation will have a witness...it may b Cabir or Mukti cant say...
