Natasha's elder sister is named Yuna.
Yuna's muscular dystrophy was discovered five years ago. After a period of treatment, there were no significant results. Eventually, the high cost of treatment overwhelmed the already not-so-wealthy family.
The parents of the two sisters, although still alive, are farmers living in remote areas. They only know that their two daughters have found decent work in the big city but are unaware of Yuna's illness.
Yuna is a dancer and used to have quite a few opportunities to perform on advanced stages, garnering some fame within the circle.
At that time, Natasha had just graduated from university and started working for a company, while Yuna, through her own efforts, had already bought a house of her own in the area.
Originally, they planned to work hard for another year or two to save up enough to bring their parents over, but everything turned into a hopeless abyss due to Yuna's condition.
