Please help me find this story

Arnav and Khushi were lovers in past. I think because of his dad's conspiracy they get separated I think some morphed picture of Khushi with someone or some message in phone I think. Arnav MU Khushi.

There is a little child too. Not their child but I think their siblings. Arnav comes in her life because of the child. I think to take the child away from her. He shows his hatred towards her but actually he was still in love with her. Gradually they clear the misunderstanding. Most of the stories happens out of India.

In this story Lavanya is pretend/contact GF/fiance he made a deal with to fool his father.

Anyone remember's this story. I know my description is so confusing. I just remember this vaguely. But please if anyone remember's share me the name and link.
