Eunji showed that she was incredibly protective of her little siblings!

She was a guest on the May 17 episode of 'Thank You'. On the program, MC Cha In Pyo asked her, "What would you do if your little brother was being bullied at school?". Eunji didn't hesitate for a single moment and replied firmly, "I'd go find the bully. One time, my little brother said that there was a bully�bothering�him and he was really big. I went to find him, glared at him and told him, 'If you bother my little brother again, I'm going to kill you'. The kid started to cry."

Looks like Eunji's little brother has someone he can count on whenever he needs!
