She became the personal trainer of the male lead who happened to be her ex boyfriend. And after solving the misunderstanding it was found that she had saved her boyfriend from drowning but couldn't wait for him to wake up from coma and another girl used this opportunity to be his fiancee. Can anybody suggest me which novel it is .
