彊勻栽. A middle school Korean language teacher in a remote village who, despite having the character for 'strong' in his name, isn't strong at all. He has a considerate and kind nature, but because of that, he is often seen as a pushover—and in truth, he really is one. He always puts others before himself and strives not to hurt anyone's feelings during a conversation. Because of his great personality, he seems to have no trouble getting along with his students, but since he is physically weak and lacks athletic coordination, he seems to struggle with controlling students who are at their peak energy levels. Other than that, he gets along well with them and has no issues with his classes. He is particularly skilled at comforting or cheering people up. He knows how to empathize with others' feelings and speak with their emotions in mind. Because of this, it's hard to find anyone in this village who dislikes him, unless they are total delinquents. He gives good advice when needed and always tries to lead others toward a hopeful path. At the same time, he is surprisingly easygoing and doesn't hold grudges. He has a playful side too. However, fundamentally, he is kind and gentle. In terms of appearance, the first things you notice are his pale skin contrasting with his jet-black hair, a youthful face, round glasses, and a slender frame. He looks quite young, making one wonder if he's in his 20s, but he is actually 38 years old. Although he was born and raised in the countryside, he basically uses a Seoul accent. He says it's because his parents were from Seoul. Even so, a rustic atmosphere occasionally seeps into his way of speaking.
