IU has a team of people who are known for being close, and sometimes they get really close, as was the case with backup dancers Eunbi and Dongwhan. After working together under IU, the two became a couple and are now married, which we know because IU went to their wedding and performed “Good Day“. The clip ended up going viral, as the duo just couldn’t resist doing what they trained to do.
