Flashback - Who is she?

When Imelda fell ill for the first time, and she was taken to the hospital.

Andy had just finished meeting with the doctor who treated Imelda. His mind was still confused by all the words and explanations of the doctor. How can Imelda have been suffering from blood cancer for a long time, which slowly continues to eat away at her body?

Even the doctor said that Imelda's chances of surviving like a piece of paper were slim. Andy is stupid, he doesn't know Imelda that well. His acquaintance with Imelda just happened when he was at Imelda's coffee shop.

A smart, friendly, and independent woman, that's all he knows. During his relationship with her, Imelda never showed the pain that she had been hiding for quite a long time. 

But the question is, why? Andy again saw the paper containing Imelda's lab results. His steps stopped when he heard a voice and looked at Putri from a distance.

"Oh..? That's Putri, she's on the phone?" Andi thought.
