Is Sonali Upen's GF?

Upen candidly said that Sonali is her GF. The way they are mingling with each other , I have no doubt that there is something special between them. Going to WR at the same time, Sonali resting her head on Upen's shoulder, Upen walking with Sonali with his hand around Sonali in GA and others stuff give enough reason for us think that they are couple now.
