So what is it between 'ShraMan'

Yup, so this is after what I read in AT of SharMan... But exactly, from whom Shravan and Suman... is "What" Love/Friendship or in between... that lingers around them... and wouldn't let them be in peace...
Smile and happiness on Suman's face was clearly indicating level of effect Shravan has on her..
But she wasn't really blushing...
and some pin of hurt Shravan has been hiding behind every time... Suman says... you only know to run away... something is there between that run away... I feel...

So.. I feel so far it's Deep Friendship, that needs to be furnished...

Well shravan already in love with her in childhood and I think sumo too but she didn't realize that

Sumo definitely loves him. But has not realized it yet.

For sumo shravan is a special friend but she not not realized what is that special bong and shravan said he love her but that was during their teenage ...they will soon realize their special bond is nothing but love.

Feel they subconsciously in love ❤️

I will go with fifth option..both love but dont realize...
