Oh my goodness! This is such a beautiful one-shot! <33
The title was the first thing that hooked me and I love how like the "fees", you've also thrown in so many other references - Shravan fixing the clutch of Sumo's car, the kulfi, the "challenge", etc. You've written this keeping the characters' personas perfectly intact, with the dialogues, thoughts, actions, everything! I really enjoyed how you've explored their relationship taking the next phase from friendship, the new awareness they have of each other and the physical attraction.
I loved how determined he was to fix the clutch to prove "there was nothing that Shravan Malhotra could not do" Typical Shravan :') Reminds me of when he tried to prove to Sumo he could cut the onions for the daal. My heart was melting when I read that they both hadn't finished watching the Harry Potter movies together and he hadn't gone to the Warner Bros studios because it was something they were going to do together. AWWW <33 There go my feels!! And eeks that kiss!! *dies* To be honest, it was something I would totally have expected of the two of them. They're passionate individuals by nature, they feel things very deeply and so I'm sure all the sparks between them were ahem...very deeply felt as well...but yaaasss, go Sumo! Love how she's not afraid to take initiative and straddled him because "if he wanted a kiss as his fees she was going to give him a proper one" I love how her initial understanding of "fees" back post-house case was that Shravan might want a kiss and you've brought that back here. Lovely job! Keep writing <3
