I can't help but admire the maturity with which Shravan has handled his first love and break-up, contrasted with how the perfectly raised Suman crumbled.
When the show started he was the cliché popular/charming/flirtacious dude who easily got frustrated and fought back. While Suman was the well-mannered 'mature' lady who agreed to be cordial with Shravan and help him out despite not liking his careless attitude. He always seemed to be the underdog, with Suman guiding him through army school, through his relationship with Devika, through morals and all. Even though Shravan did teach her how to enjoy and follow the heart, Suman always had the superior grip on life, being able to balance fun with her army goals.
But oh how the real faces came out once Shravan fell in love with her. He seemed to mature almost instantly - acknowledged his emotions, changed his carefree behaviour and ways, started working on improving their relationship, etc. I would not have expected that of the Shravan I saw in episode 1. But he outdid himself. That love for Suman and passion to win her brought out his potential to be highly capable, both emotionally and professionally (top-cadet). He mellowed down drastically and used his strong heart to fire his brain into action.
And Suman, once realizing her potential feelings for Shravan, became a mess. Fever, confusion, anger, what not. All her maturity, preachings, stability washed away with the mere thought of being in love. Of course once she confessed and they were together she got her sanity back, but she was never really the same again. Not that her academics or army dedication suffered, but she lost the self-discipline and thoughtfulness that defined her. Her missing that class in the last week, her assuring Shravan that it's okay to run away. That was not the Suman in episode 1 at all. Like someone mentioned in the forum, her army upbringing had restricted her ability to deal with emotions. And it seems, once her heart began beating she couldn't get it to listen to her brain again.
I think that set-up pre leap well explains the way our captains are coping with the breakup now. Shravan thinks fondly of the time they spent together, as seen while talking to his friends and in the precap "Cheezein khatam hojaati hai par acchi yaadein hamesha rehti hai". Clearly he accepts that what they shared was amazing not a mistake, he enjoys those memories. And he looks at her with the same intense love. I don't find him bitter actually. The way he tells Bunty he doesn't want to talk about her, the way he walks away from his friends, the way he slyly taunts Suman, the way he tells her that he wants to leave asap - it shows that although he is disappointed in her and how she broke them up, he wants to be practical and move on because there's nothing left to fix. It was a thing of the childhood and it ought to stay that way. Him calling it 'their paagalpan' is quite mature honestly, because I think he realizes that their love didn't really have the strength to overcome hurdles. And by including himself in that phrase, he implicitly acknowledges his own failure to hold on to the relationship as well. He has trained his brain and heart to reach a compromise and balance. (I think his risk-taking behaviour is not to do with Suman really, but perfectly aligned with his personality from episode 1, like Bassi said about his 'sankiness'. That's what he always loved. Even though he spoke of going to America to chill, we knew he loved listening to his heart and being carefree).
Suman now, completely baffles me. Probably because she is so baffled with herself. Her brain hasn't completely taken over and her heart hasn't stopped beating for Shravan. She doesn't forget his memories but she doesn't enjoy them either. She has succeeded in the army yet she hasn't regained her self-discipline or thoughtfullness from before. She's the same mess she was when she didn't know her feelings for Shravan. She actually comes off as bitter, trying to get one up on Shravan who tries to shrug it off and move past.
As for the reasons why - regarding their family upbringing, relative losses and support systems - I think that's been nicely addressed in the forum many times in the past few days. I just wanted to talk about how love changed them, and not the incident itself.
Sorry if I made anyone roll their eyes with another analysis post.
