Singer ZICO has fulfilled its pledge to win first place for its new song "Summer Hate."

Zico visited his home for the "Dance Challenge with Jang Sung-kyu's Son," which he made as the No. 1 pledge when he appeared on MBC FM4U's "Good Morning FM Jang Sung-kyu" on the 1st.

Zico, who appeared comfortably in a signature T-shirt and shorts from his new song "Summer Hate," said, "I didn't know the day would come when I would keep my promise. I expected it, but I'm so happy and grateful that you've given me so much attention to carry out my pledge so quickly.

Jang Sung-kyu also welcomed Zico as "a man who keeps his promise," and introduced his family motto, "Zico Seokja," to make people laugh.
