[A straightforward romance about a wealthy younger man who falls in love at first sight with an indifferent female lead] "It's not like I'm asking for your phone number... Just your name! P-Please, can't I?" A man suddenly appeared before her and asked for her name. The business card he handed her read, 'Cheon Ha-kyung, Director of Cheonhae Group.' She'd heard the Cheonhae Group has three sons, but... Could a man this handsome and young really be one? Could he be an impostor? "Goodbye." Two weeks after parting ways with the mysterious man, he joined Ina's Management Support Team as a new employee. Contrary to her expectation that he would flirt all day long now that he was her subordinate, Ha-kyung only sent her burning gazes without playing any cheap tricks. "I have no intention of just dating. Someone else would be a better match for you. "I... um. I-I like you." "What?" "I want to do it. Marry you, Senior."
