WHO WAS I

The story is all about the life of two girls who crossed their lives before the death of one of them. The first girl had a car accident that made her comatose for 2 years. She's from a poor family and cannot afford the bill in the hospital. While in another room, there's a patient who has wealth. She has a heart problem. She needs a heart donor. Year by year, the doctor discovers a lot of dysfunction in her body due to the fact that her heart couldn't function well. One day, the girl in comatose woke up. The girl from another room was free to go everywhere since she almost lived her life in that ward. She's the one who discovered the awakening of the coma girl. They became friends when the coma girl was doing her therapy at that hospital. They became best friends. They spent 1 more year in the hospital. The girl in coma recovery was doing fine. Until one night, she was accidentally swept on the floor that caused her to be comatose once again. The bleeding on her head was continuously damaging her brain. Because of this, her best friend had a heart attack. They both entered the operating room. The girl in comatose was in critical condition with 50/50 condition. While her best friend who had a heart attack will only have a chance of living if there was a heart donor-but it was impossible since they can't find a donor. Hours had passed and only one door had opened with good news. Who do you think she is? Is it the girl in comatose or her best friend who has a heart problem?
