Su Ruanruan's younger half-brother, seventeen years old, slightly taller than Su Ruanruan at a little over 1.7 meters. He is extremely thin like a monkey despite receiving all the best food in the Su family. He is spoiled, lazy, has never earned a single work point, and idles about every day. He failed his exams after middle school and has no intention of studying further. He shamelessly demanded Su Ruanruan's watch for a blind date and threatened to tell their parents after being rebuffed.
