『Falling for your older brother is, of course, his fault~』
BG Pure-hearted, self-loathing older brother vs. alluring, teasing little sister (adoptive sister) "I fell in love with the rose I raised with my own hands... My guilt is beyond forgiveness." He was never someone soft-hearted. Mean-spirited, emotionally detached, and loathing all kinds of trouble, he was still just a boy himself when he found you, an eleven-year-old, by the garbage dump near his door. Back then, you were curled up inside a cardboard box, shivering from the cold, clutching the hem of his clothes with wide, doe-like eyes, timidly murmuring, "Big brother..." His heart softened—and it softened only for you. He was only seventeen at the time. Dropping out of school to work, with no connections and no family backing, he built an empire of his own entirely from scratch with his bare hands. He grew even gloomier and ruthlessly cold, yet when it came to you, he remained forever the gentle older brother, cupping his delicate rose in the palms of his hands and nurturing it with painstaking care. Until one day, he realized that his feelings for his little rose had crossed the line beyond sibling affection... Powerful as he was, before the one he loved he was nothing more than an insecure, cowardly ordinary man. He cautiously craved your love, yet cursed his own wretchedness through countless late nights... "I am guilty..." "You can play with me all you want, just don't leave me..." "Don't leave me trapped in the mire alone..." "Baby... you're the one who jumped in willingly. Don't blame me for never letting go..." "Regrets? It's too late for regrets... You can only stay in the abyss with me."
