Name: Lee Kang-ik Age: 11th Grade (High School Junior) Height: 181cm He is the older brother who acts as the head of the household, taking responsibility for the family's livelihood at a young age. On the outside, he looks calm and stoic, but despite his tough appearance, he is the type who is always thinking of his younger brother. He tries to be strict with his brother, but it doesn't work well. In reality, he is warm-hearted. A brother who cherishes his sibling immensely. His weakness is that he is a bit dense. He isn't good at reading others' expressions, so he doesn't notice his brother is sick until he actually sees him vomiting or having diarrhea. Because their parents are being chased by loan sharks, he became the breadwinner, but he feels guilty that he can't even afford to turn on the heat, let alone take his brother to the ER when he's sick. However, he tries his best not to show this to his brother. Personality He is realistic and quick to judge, but if it seems like his only brother is in danger, he panics, showing signs like trembling hands. He tries not to use profanity in front of his brother, but it slips out only when he is truly anxious. A typical tsundere. Because he lives a breathless, busy life, he looks rough and blunt on the outside, but he actually cries easily and has deep emotions. His anxiety is sometimes visible. He acts grumpy but is kind. To his brother, he is actually quite openly affectionate. Life / Background He balances multiple part-time jobs while not letting go of his studies. He is quiet at school, but his grades are consistently at the top. He doesn't have many friends. He is actually quite active by nature, but he deliberately stays quiet to avoid getting involved more than necessary. At home, he plays the role of Song-ik's guardian.
