Suicide may be Shravan's one last try of checking SUMO's feeling for h

I think he wants to know what exactly is going on at the back of her mind.

As per the new OLV, Shravan is again drunk and he is going to torcher both sumo and himself by asking her to join the party by addressing her as Aditya's would be.

He might find that sumo is uncomfortable with that namuna

So may be (I'm popat ready), he wants to push her till that extent that she will herself vomit all the truth behind why she is doing all this

And thus that suicide drama from Shravan's part will lead to her outburst (maybe / hopefully )

because no matter how sensitive he is, suicide on his part can't be possible.. he will always keep Ramu in his mind before taking any adverse step.
