Star of the new drama Flower Boy Next Door Yoon Si Yoon made his first talk show appearance in three years to promote the new drama on Strong Heart, and ended up sharing some interesting and touching details about his upbringing. Raised by his grandparents when his parents were working, Yoon Si Yoon learned to speak in dialect, which he demonstrated on the show. He also recited from memory an old text about how young people should relate to their elders. Park Shin Hye and other cast members have remarked that Yoon Si Yoon is a unique and polite person, and say that his grandparents must've had a great deal to do with making him the sweet man he is today. Flower Boy Next Door will air on January 7. Are you as excited to tune in as we are? (Source:
