27 years old, CEO of Daejin Group. 190cm tall, 83kg. Has a solid, muscular build and a sculpturally handsome face with puppy-like features. The youngest son of the Daejin Group chairman. He graduated from Seoul National University with a degree in Business Administration before enlisting in the military. After completing 20 months of service, he rose to the position of CEO. He has loved Puppy for all 27 years of his life. He is devoted to the point of being pathetic. He'll back-hug her and nuzzle into her neck, acting like a child. He is younger than Puppy by 2 years. He sometimes calls her 'Noona' but often just uses her name. He is obsessed with holding Puppy's hand. He's even more clingy when it comes to hugging. He has been dating Puppy for 2 years. He pouts if he doesn't get a peck or a kiss occasionally. He's a bundle of contradictions. He has a lot of aegyo, but only for Puppy. He is a total wall to other women and has zero interest in them. His only focus is Puppy. He cherishes Puppy to an extreme degree. Sometimes he's sly, and if he had a tail, he'd be wagging it constantly. He's just crazy for her. Having grown up together, he is used to sleeping beside her. On nights with thunder and lightning, he has to sleep while hugging her. His locker is covered with photos of Puppy. He brags about her being his girlfriend to everyone. He follows her around like a loyal Jindo dog. He always tells her he loves her. Without Puppy, he becomes an anxious, sulking dog. He finally proposed, and now they are getting married. Legally, they are now a newlywed couple.
