His cruel destiny

It started when Natasha (main lead) went to the restaurant where she has been working as a waitress for 3 years.She has only one friend and no family. Her parents left her at the orphanage. A person offered her a place to stay and work. Liam (main lead) on the other hand is a total womanizer. They are friends with Adam, who wanted Linda and Liam to get married. Liam bumped into Natasha the next day. He asked for a date and she agreed. He took her on many dates where he showed her his gentle side. He lied to her about being an orphan. He kissed her and told her that he loves her. She told him that she also loves him. He took her on a date where he gave her a promise ring and told her that he would marry her. She believed him and agreed to have sex with him because she loves him. The next day when she woke up, she found that she was alone. She didn't get any message from him and her friend told her that he had done that to have sex with her. So, what on earth is going on here?
