Because of emotions

Na-hyeon, who had no feelings as a child, was a source of great worry for her parents. One day, when her parents passed away in an accident, Na-hyeon was raised by her aunt, and losing her parents at a young age was even more devastating. But as Na-hyeon's heart hardened and she began to lose her friends, someone appeared who could open her heart... and what a surprising twist?! It's also filled with humor, so please enjoy it! ^^
