Hi!
Honestly?
If Karan got married/proposed to Shraddha then (of course) I'd be heartbroken 😉 😆 But happy for them both... Kyunki they both sound so in love with each other... Aur if Karan & Shraddha are happy then I am too... I'd wish them all the happiness in the world... You're right this is reality aur reality mein he's probably never gonna meet us or anything ðŸ˜...
As for Karan & Shilpa getting together... Aisa Karan kabhi nahin karega... I don't think he'd (intentionally) break Shraddha's heart (remember the recent interview?)
Take Care!
Love, Hope & Best Wishes
