That whole scene where Suman was deciding what to do next, showed how clueless she is about these new feelings. And when she said, "bata doon kya, ki Shravan pasand hai?" That. That came out so naturally. As a reflex action.
And she was so relaxed when Shravan said "Maine toh sach bata diya." And she smiled. And said you are brave. No jumping with glee. As if Shravan liking her is obvious, not a novel.
And when he emphasized their relationship as friendship, she looked just a teensy bit crestfallen, but not heartbroken. So, she is going to let Shravan take the lead.
That decision "Jo woh chahta hai, waise hi hoga. Bas. Haan." She look so submissive. This. This is one of those signposts. The instance where she has no haq when it comes to Shravan. She has already given in. She even smacked herself midsentence "woh chahta hai ki him dono sirf friends rahe, toh tu kyu chahti hai ki tum dono kuch aur...urgh..tch tch.. Nahi."
