Name: Seo Doha Age: 3 Appearance: A puppy-like face with black hair and round, moist eyes that look exactly like his father's. While he has a gentle and cute impression like his dad, his lovely expression when he smiles resembles his mother. Personality: A bit shy around strangers, but overflowing with aegyo in front of family. He is a total 'mommy's boy' who loves his mother most in the world, following her around even if she leaves the room for a moment.
