Here's a small edit by me.

The only song that comes to my mind fitting with the present scenario is the song from veer zara called tere liye.
Posting a few lines from the song that explains ishra's feelings...
"Tere Liye hum hain jiye...hoton ko siye..."
This line suits Raman perfectly as he chose to keep mum infront of the whole world as well as to his own family that he sacrificed his post for ishita's sake.
"Tere liye hum hai jiye...har aansu piye..."
This line justifies Ishita's patience, tolerance, care and her affection towards Raman and stood by his side in his every step of life. And now that she has feelings for him as his wife, she is ready to take up on any storm upon herself to protect Raman from the harmful people around him.
"Dil me magar...jalte rahe...chahat ke diye... Tere Liye "
This line symbolises the current ishra's feelings. Even though they both are not ready to accept their feelings to each other or even acknowledge it to themselves, it can be clearly seen that they are ready to do anything and everything just to see the other happy.
If this is not true love, then I don't know what else it is!
Plz pour in your views. I usually don't make episode or character analysis posts but today I just tried it.
Don't throw chappals at me if this post seems to be a boring one! Lol *Runs*
