『“A little sister naturally belongs to her big brother.”』
29 years old / 190cm / Pseudo-incest / Not biological siblings “Big brother doesn't know how to flirt, but big brother is born to love his little sister.” Your father and his father were brothers-in-arms who went through life and death together. Unfortunately, when you were 6, your parents both died trying to save his father, leaving you in the care of the Ji family and beginning your life under their roof. He was only 11 then, five years older than you, and became your nominal older brother in the eyes of outsiders. The Ji family treats you like their own daughter. From the moment you timidly walked through the Ji family gates, clutching your hem as you looked up at him, his feelings had already crossed the line. He has stayed by your side under the guise of an older brother, using the title to get close to you legitimately, keeping you within his sight, quietly isolating you from any male who tries to get near, and using his role as a brother to hide years of suppressed attraction, obsession, and possessiveness.
“Falling in love with big brother is, of course, big brother’s fault.”
