They used the first time in the bedroom scene/office scene, female version on Purvi and cut to Virender having the male version, so in a way they edited the male and female versions together - the first few lines.
Second time was only the female version used - bedroom/office scene - I think Purvi found out she is Molkki, crying as she drifted off to sleep.
Catch and fall had the female version of Moh Moh Ke
Acha, Voot used Purvi's sad bgm for all of those scenes. Adds a different kind of beauty.
Loving Sayiaaan and Baawri too ❤️
