Natalya
A Natalya is a normally cheerful person who tends to bottle up their emotions. They're always kind to others and put their friend's & family's happiness above their own. A Natalya could be depressed and you'd never know because they're good at acting and putting on a smile. They're good listeners and love to help others, but don't get on a Natalya's bad side or you will deeply regret it.
Person 1: Wow, she's such a Natalya. Helping her friend get with their crush.

Person 2: Wait, Doesn't she have a crush on that person too?

Person 1: Yup, but she'd rather make her friend happy than make herself happy.

Person 2: You're right. She's such a Natalya.
