ZE:A's Siwan revealed an awkward quandary for himself and his sister!

Appearing for an SBS radio broadcast, Siwan told the tale of how his sister was often confused to be his significant other.

"My sister is on the pretty side. When we're together, many people confuse her as my girlfriend, while others recognize us at once as siblings," he told the DJ, Park So Hyun.

That wasn't the end of family similarities, however, as he also revealed that his mother and father also looked very similar to each other.
