I never think that Daksh will fall for Sonakshi in any case. First of all, she is not his type. Second she is too immature in behavior. He started to love Naina not just seeing her outside beauty. He saw her heart and that beauty attracted him. The development of his feelings was slow and steady and now it is strong. Comparing to Naina, Sonakshi deos not have any single quality of Naina that he admires. Naina is simple, polite, bold, loving, self-disciplined and kind. While speaking to her, she shows enough patience to listen. Moreover, she understands him more than anybody. Daksh likes her maturity in handling things. Like him, Naina is also not a show-off person. I don't think that by taking Akruthi's case Daksh will fall for Sonakshi. If Sonakshi thinks so, it is only a misunderstanding as she does not know them very well. Then one thing is, she can blackmail him taking this matter. But that does not mean that it is love right?
I feel, Daksh will say the matter to Sonakshi as he promised to Naina. I wish it happens. Coz, after telling the matter, they can understand that what the real Sonakshi is!!!!
