Rib Youth

A reunion of four college roommates three years after graduation tears open their seemingly respectable but actually broken lives. Every episode has conflict, every unit has a twist, every character has an arc, and every foreshadowing pays off—no filler, with all mundane details setting up major later reversals, gripping viewers through empathy, curiosity, and reflection. The four characters mirror each other's personalities and check each other's fates; there are no absolute heroes or villains, only ordinary youths swept up by reality. Each person's predicament stems from their own character, and each one's growth comes from overcoming their own flaws. — Description from novelcodex.org
