Let's take a flash back! Sonali in the first week was not seen much and as a result she was evicted in the very first week. She returned to the house in next week and, Oh boy! she was back. Due to Gautam and Diandra tiff Sonali acted smart and increase her proximity with Gautam. Sonali had once proposed Gautam on the show, not only this, they also had some cozy moments, but it didn't last long, Sonali noticed Gautam didn't deny or accept her proposal, on seeing that he is not really showing any further interested in her, she changed her track and started increasing her proximity with Upen Patel.
However, Sonali and Upen do share a hate-love relation. From giving Upen a passionately kiss during a task (luxury budget) or sharing a cozy bed moment with him, Sonali had done it all.
Later, their (Upen -Sonali) equation changed, when Sonali pleaded Nigaar to save her instead of Upen. He was seriously offended and furious, this episode had triggered a huge fight between the two. And their relation hit the rocks. Albeit, Sonali did try to revive her friendship with Upen, but he did not pay any heap to her.
Recently, Sonali and Upen were again seen engrossed in love talks. During the luxury budget task Upen was joking around with his besties Dimpy and Karishma and he referred Sonali as her his girlfriend in front of them.
While, Sonali was sitting on the dinning table, Karishma noticed a red mark on Upen's neck. When Karishma inquired about the mark he admitted that Sonali had given it to him. Yes Sonali had given Upen a love bite! After the confession, Sonali started blushing.
Well, Well, Well! We don't know whether Sonali is an innocent girl searching for love inside the house or is this her game plan, we don't know what it is exactly, but all we know is whatever it is, it is surely working in her favour!
