Sumo didn't see the facade but Bunty did because Shravan was more open with him and the hurt was literally on his face but with Sumo, no he wasn't himself but pretending to be one because her happiness matter. We can't really compare the friendship of Shrunty and Suvan here. Suman has never explored this attachment to any of her best friends because she knows that Shravan is better at it. "Tum rishte nibhaana jaante ho". We can also see that Shravan and Bunty has spent more time compared to Suvan and hence their bond is stronger. Bunty has seen Shravan's tantrums, his sadness, his feelings getting developed for Sumo. But has Sumo seen those ? No. She has only seen the kind of heart Shravan has. She has seen the showoff Shravan getting evolved as a person and realizing herself that he's always been a great friend and son. 
One of my teachers in school got in the conversation about good friend and best friend. He said a best friend will always have your back and will go along with whatever you go with because of the bond you share. And a good friend might not do that always. He/she makes you evolve as a person rather than going along with you on everything. Guess this is what Shrunty and Suvan's equation are. Yes, Bunty always tries to put Shravan on his ground whenever he goes overboard with his expectations around Sumo. But Suman has managed to bring out the different side of Shravan. The less showoff, the more humble, the more of a side which was always there deep inside but wasn't in open. 
Hence, Sumo and Shravan does not share the best friends forever friendship which they claim. They share a whole different side. Yes, had they been childhood friends, the equation would have been same as Shrunty but here, it's one sided love and friendship mingling together and still being best friends.
