I watched a movie in the 90s about a brother and a sister who recently lost their father and the sister being the older one moved to the city to inform the brother and also live with him but only recently found out he's engaged to a girl. She though having some emotional feelings for the brother tried hiding this feeling and ended up making out with the brother's best friend to the brother's watchful-eyes. This in turn made the brother obsessed over the sister and wanted to make out with her at all cost, which she eventually allowed him but only because she didn't want him to hurt himself. And after that she had to disappear from his life. Please can anyone tell me the name of this movie
