As we know that salve's to be husband is going to enter lrl.
it seems ovious to me after yesterday's epi that ritu told raj that she is in love with him and maybe he disagreed and didn't say anything because of Naina's presence.
maybe because raj did not give a positive reply salve's to be husband is entering lrl as her temporary pair to make raj jeleous.
if this is not the reason then i don't understand why that guy has to enter lrl.
plz do comment
