On the upcoming August 14 broadcast of tvN's 'Amazing Saturday - Doremi Market', Red Velvet's Joy and Yeri are expected to enrich the episode with their charms.

On this day, Yeri drew attention by announcing that in preparation for her first appearance on the show, she completed a preliminary investigation of the show. Yeri revealed that according to her investigation, the show completes filming very early and offers a lot of delicious foods. In response, Joy stated, "In broadcast shows that complete filming quickly, Shin Dong Yup is always there."

Yeri reportedly brought laughter in the filming studio when she confessed that she has terrible hearing, and even attempted to 'cheat' during the lyric-guessing game. On the other hand, Joy brightened up the atmosphere through her 'sexy dance' performance, and showed a surprising collaborative dance.

Meanwhile, 'Amazing Saturday - Doremi Market' airs every Saturday, at 7:40PM KST.
