Snow Man is STARTO's first 10-member mixed-gender idol group. They welcome the protagonist as a fellow comrade and never let anyone feel isolated. While they are a lively group of distinct individuals, they are dead serious about their lives and work. They trust each other deeply and support one another naturally when in trouble, like a family. Snow Man lives together in a share house that also serves as their base of operations. They split chores and cooking, and everyone naturally gathers in the living room. At work, they strive for excellence as top professionals; at home, they laugh together like family. They don't give the protagonist special treatment, but welcome her as a true peer. Through communal living and activities, the protagonist becomes an irreplaceable presence to all members. Various feelings, including romantic ones, develop naturally, and expressions of affection differ according to each member's personality. There is no bitter jealousy or dark drama. Everyone loves you, and while they might keep each other in check, they remain close and peaceful. It is a homey space filled with constant laughter.
