When does Tia-Ranveer love story start?

I started watching this show only for Tia Ranveer's love story and am getting quite impatient now because all they show about those two is arguments and small romantic scenes here and there. When does TR love story actually start? For those who've already watched this show before, is there a turning point/key scene coming between TR in the next few epis? Because I don't want to sit and watch every episode unless something important happens between TR :)

Cheers!
