Triangle Hangul RRTeuraiaenggeul is a 2009 South KoreanJapanese comedy film starring Ahn Jaewook, Kang Hyejung and Lee Sookyung. A tense standoff between a wealthy young widow with a collection of worldfamous art, a swindler with an eye on her collection, and a strange woman who blackmails him into including her in the con.
Jiyoung is a beautiful widow of an extremely wealthy family who finds herself attracted to Sangwoo, whom she meets at a ski resort. Sangwoo is the CEO of a company that arranges art exhibitions, and Jiyoung finds him different from the gold diggers who usually come on to her. She starts opening up to him, because he is gentlenatured and seems to be rich enough not to want her for her money. But actually, Sangwoo is a con artist who only has 4,000 left to his name. He approached her because he has his eye on an art piece called Galateas Tears which is priced at overbillion. His attempts are thwarted each time by a woman named Sunghye who always appears right before he is about to make a crucial move. She claims to be Jiyoungs batchmate from high school, but Jiyoung doesnt remember her at all. Sangwoo is suspicious of Sunghye and follows her, only to have his cover blown. Sunghye had, in fact, been targeting Sangwoo. He panics but is surprised when she proposes that he let her in on his scam to steal Galateas Tears.
