questions bout' march 13 episode ????

sorry for this dumb questions

I started to watch this show recently. In march 13 epi. they show how Heer is wearing a wedding dress or something and prem were holding hands and how some comes and take Prem away and they slowly seperate. And also the part were heer is wearing a nice dress and how prem pulls her(not at the engagement. this one was different). I was wondering were those parts came and what were they about??

Can you guys help me.I would really appreciate it.

Thank you so much 👏 😊
