The promo is from Sai's perspective, she is not sure of Virat's feelings, she thinks that Virat left Pakhi (opposite happened but makers like to shove that narrative). She will go to his room tomorrow, when she finds him ready to leave for mission. Pakhi might use this as opportunity to instigate her that Virat did not want to live with her in a room, hence went for mission. Then post mission, Sadanand might die or mission fails, Virat comes indifferent...Sai feels sad and Pakhi adds more fuel to fire. Aur uspar agar sadanand ki wife bhi aa gayi CN 🤪
