Triangle is a 2009 South Korean-Japanese comedy film starring Ahn Jae-wook, Kang Hye-jung and Lee Soo-kyung.

Plot
Ji-young is a beautiful widow of an extremely wealthy family who finds herself attracted to Sang-woo, whom she meets at a ski resort. Sang-woo is the CEO of a company that arranges art exhibitions, and Ji-young finds him different from the gold diggers who usually come on to her. She starts opening up to him, because he is gentle-natured and seems to be rich enough not to want her for her money. But actually, Sang-woo is a con artist who only has left to his name. He approached her because he has his eye on an art piece called "Galatea's Tears" which is priced at over. His attempts are thwarted each time by a woman named Sung-hye who always appears right before he is about to make a crucial move. She claims to be Ji-young's batchmate from high school, but Ji-young doesn't remember her at all. Sang-woo is suspicious of Sung-hye and follows her, only to have his cover blown. Sung-hye had, in fact, been targeting Sang-woo. He panics but is surprised when she proposes that he let her in on his scam to steal "Galatea's Tears."
