Coming towards Suman. When Shravan congratulated her, you could see the teary smile in her eyes that depicted how grateful she was to him for doing this. Their interactions never needed a "thank you" to convey how much both value each other. When Shravan was leaving, Suman's eyes were constantly looking for him and yet she couldn't stop him. She got reminded of how Shravan claimed that he will leave once she gets okay.
Today Suman came to a realization, that in the midst of all her illness, she forgot the problems they both had with each other. She had gradually warmed up to him and she had started treating him as her best friend again, her anchor, the most important person in her life. There was confusion on her face, and somewhere sadness too. She did not want to revert back to the situation where he was distant and cold with her.
Today's scene at the end was somehow symbolic as well. It gave an insight to what their life will lead from now on. He did leave but before leaving he made her value his presence in her life again. All these episodes proved that sometimes a spoken apology is not necessary and actions definitely speak louder than words. This time Suman is going to bring him back and make him realize that their relationship is beyond these misunderstandings and they should give it a try again. I think their story will begin from here with a much stronger foundation of friendship and trust.
P.S: I don't know how much of it made sense. Would love to know your thoughts. Wasn't that happy the way Sumo recovered but the last scene with the title song was my favorite from the episode. Hence, my analysis on it :)
