This track reminds me of a similar track in guddan tumse na ho payega.
They showed a very dramatic promo of Akshat (ML) shooting Guddan (FL) and her falling of the cliff and the same was shown in actual episodes as well.
Guddan came back a month later and still trusted Akshat and her love that he could never do something as bad as that with her. She kept trying to get the truth out of him and find out who was compelling him while Akshat pretended to hate her but she didn't give up till the end. In the end it was revealed it actually wasn't Akshat who fired the shot it was Guddan's sister Revati was was hiding behind she wanted to kill Guddan because she believed she was responsible for her fiance Angad (Akshat's brothers) death.
Akshat wasn't telling Guddan about Revati because he knew she loved her sister a lot and wouldn't be able to take such a shock so he took the entire blame on himself and confessed in front of her that he wanted to kill her because he hated her. When he saw that Revati was shooting he pretended to shoot as well because he didn't want her to know her own sister wanted to kill her.
