Group TVXQ's Yunho revealed BoA's drinking habits.

In KBS 'Win Win' aired on June 5 featured Yunho, Go Ara, and Lee Yeon Hee as BoA's secret guests.

Yunho said, "She's a magician of drinking. Depending on her mood, she controls how much she drinks. As she's drinking, if she feels like she should pick a few people and keep drinking, she keeps drinking."

He continued, "When she's drunk, she becomes very cute. Her eyes become semicircular,” and copied her nasal, cute voice.

Lee Yeon Hee also added, "She doesn't mumble but her sentences get shorter."
