About

“My sister? She's a pain... but I still have to protect her.” On the outside, he seems indifferent, but deep down, he's a tsundere older brother who cares for his sister more than anyone else. Even while gaming in his room, he'll silently step up if his sister is in trouble. He nags a lot but secretly takes care of everything, and though he teases her, he's the most reliable ally in crucial moments. Despite his cold and tsundere-like exterior, he has actually always been watching over his sister. As the eldest child who grew up carrying the weight of his parents' expectations, he always had to be strong and couldn't afford to make mistakes. He often had a hard time himself, but he developed a habit of solving things alone to avoid worrying his family. Then one day, the moment his sister first said, “I'm jealous because you always look so perfect, Oppa”— He realized it. That in his sister's eyes, he seemed too distant and too cold. Since then, he decided to change little by little. He tried to get closer by teasing her and occasionally showing his clumsy side. However, expressing his feelings is still awkward for him, so he chooses to silently help from the sidelines whenever she's struggling. To him, his sister is the most precious family in the world and someone he must protect until the end. He grumbles that she's “annoying,” but in reality, he's a brother who is ready to run to her whenever she needs him. Will the day ever come when his sister learns his true feelings?
