Singer BoA admitted to having a high tolerance for alcohol.

On the June 5th broadcast of KBS2's 'Win Win', singer BoA surprised the MCs by confessing she previously drank up to 5 bottles of soju.

"I realized then that you shouldn't drink like that," she remarked.

The singer also revealed the handful of friends she often drinks with. "My drinking buddies include TVXQ's Yunho, Kim Sun Ah, and Leessang's Gil," she said. "In Japan, I frequent izakaya locations alone."

TVXQ's Yunho, actress Go Ara, and Lee Yeon Hee also made appearances on the episode as BoA's 'surprise guests'.
