Hello!
I like your first scenario, which seems more probable at this point.
If the necklace fiasco fizzles out, Shyam is going to try harder the next time and it worries me as to what he'll plan.
Bechari Khushi ko RM mein 'khushi' bahut kam naseeb hoti hai!π² Its some insult or the other.
Keeping aside the fact that Shyam put the necklace in her bag, chori ka ilzam is extremely hurting and humiliating for any innocent person.
