At the rewards show (and yes, this was their POV, in my first Taennie), Red Velvet was at the middle row, listening to the announcer. After the announcer said the name (BTS of course). Everyone claps for them, as the BTS members walks to the stage. Seulgi looks and her right, and saw Irene with a disappointed face. Seulgi was wondering why Irene was like that, so she whispers to her ear

Seulgi: Unnie, is everything fine? Why you look so disappointed?

After what Seulgi said, Irene looks at her with a smiles, showing to her that she's fine. And point at the stage to tell her to listen. In about awhile, they walk out. As Red Velvet was talking and laughing, Seulgi notice Irene disappointed face again, so she walks up to her, and puts her hand on her shoulder

Seulgi: Unnie, are you okay? You look so disappointed, did something happen?
