[@txpiocapearl]

ㅋㅋㅋ I feel like their sibling energy really shines through in this video; Sang Heon is very pouting younger brother to Gia here and she gives such teasing big sis vibes 😂🥹❤

It's so wild that they are siblings who seem to have grown up together but have two completely different accents.
