Seohyun and Hyoyeon look cute in sportswear

They still look gorgeous even in casual clothes.

On June 8th, Seohyun tweeted,"The weather was cool and nice so we went out to exercise at the stadium~!!^^ㅎReminds me of my old school days~ ㅎㅎ Everyone has a good day♥" and uploaded a long a photo.

Seohyun and Hyoyeon were sitting on blue chairs and showed their bright smiles towards the camera. Especially Hyoyeon even rested her head on her dongsaeng's shoulder, which made the photo even cuter.

Meanwhile, Girls' Generation is still busy with their 3rd Arena Tour in Japan.
