Heart (2006)

Rachel and Farel have been best friends since they were kids, often playing basketball together. But their friendship hits a rough patch when Farel falls for Luna, a beautiful new girl. Rachel is kind of boyish, who's not too fussed about her looks. She tries to help Farel win Luna over, even though she has a secret crush on her best friend.

Rachel's feelings for Farel grow so strong that she even starts changing her style to be more feminine, like Luna. But this only makes Farel see her differently.

Things come to a head when Farel and Luna become a couple, leaving Rachel heartbroken. In her upset, Rachel has a serious accident. Meanwhile, Luna is facing her own struggles with a life-threatening heart condition. How will this love triangle resolve?

"Heart," directed by Hanny Saputra, is a romantic and emotional film that was hugely popular when it came out. It beautifully explores themes of sacrifice, friendship, and complicated love, backed by powerful performances from its lead actors.
