I felt subconsciously Shravan is happy about his Marriage with Sumo. All his attitude towards Suman is just his anger & Mask.
Today's episode way he told Aditya that leave him as he wants to take Sumo home with him as promised to Nanu...
Also in precap when he comes back & tells Nanu that shall I take my wife now... it felt he is actually in peace as sumo is permanently his..
Just he want to teach sumo lesson so masking his real feeling with his anger...
