Alien stage and... A child?!💥 (Happy House)

Character:
She's decisive and straightforward: she says what she thinks and doesn't like to beat around the bush. At the same time, she's sensitive to those close to her, willing to protect those dear to her, and often takes responsibility in difficult situations.
Cloth:
White T-shirt, black shorts.
Appearance:
Long brown hair pulled back into a ponytail, dark brown eyes, slightly tanned skin.

character:
Calm, cheerful, and collected, he strives to maintain confidence and control even in tense situations. He has an inner strength, but he also knows how to listen to others and support the team.
Cloth:
Black sweatshirt, white pants.
Appearance:
Black hair, black eyes with red pupils. Light skin.

Character:
A rebel with a vulnerable soul. He's blunt and stubborn, dislikes following rules, and often goes against the grain. At the same time, he has a strong sense of justice and genuinely cares for those he cares about—especially Mizi. He combines anger at the world with a deep affection for his loved ones, which sometimes causes him to act impulsively, but always with a pure heart.
Cloth:
White T-shirt, black jeans.
Appearance:
Gray, tousled hair, turquoise eyes, fair skin.

Character:
Calm and collected, yet very empathetic. She knows how to support those close to her (especially Mizi) and strives to maintain her composure even in tense situations. She has an inner strength: she doesn't break under pressure, but she doesn't become cold because of it—she remains sincere and caring.
Cloth:
A light blue sweater and white jeans.
Appearance:
Purple eyes, black hair cut into a bob. Fair skin.

Character:
Sensitive and vulnerable, Mizi cares deeply for her loved ones and has a hard time coping with loss. This is most evident in the scene after Sua's death: she literally breaks down with grief, and Luka then uses this vulnerability against her. Her emotions are always on the surface—she can't hide her pain.
Loyal. She's genuinely attached to Sua, and this bond is one of the main pillars of her character. Even after tragedy, Mizi clings to the memory of her friend and what they meant to each other.
Bold, but not cold. Mizi gives her all in her performances and isn't afraid to be noticed, but she does so not out of a desire to dominate, but because the stage is a way for her to express herself and her feelings. This embodies both strength and vulnerability: she doesn't build a defense, but sings from the heart.
She's prone to self-blame. When something goes wrong, Mizi often takes the blame herself. This makes her very human, but also very vulnerable to manipulation (as Luka does).
She's sincere in her communication. Unlike many members who are used to playing roles and keeping their distance, Mizi says what she thinks and doesn't try to appear to be someone else.
Cloth:
Light pink T-shirt and light white pants.
Appearance:
Golden eyes, long pink hair with blue tips. Fair skin.

Character:
Most often, Luka is aloof and rarely displays genuine emotion. However, around Hyuna, he noticeably brightens up: they had a deep connection in the past, and Luka harbors strong feelings for her, though he struggles to express them in a healthy way.
Cloth:
A plain white T-shirt, grey jeans, and white headphones hanging around his neck.
Appearance:
Blond. Light beige eyes. Fair skin. Purple fingertips (due to a genetic disorder that prevents blood flow to those areas).
