Lucky you, who made a post as the 250000th question! The most common approach for the phrase "Nice to meet you" / "Encantado/a de conocerte/la/lo" (similar to your proposed sentence) in KR would be 만나서 반갑습니다./반가워요. If the term "happy" is preferred, it would become 만나서 기쁩니다./기뻐요. === Que tengas buenos días. / 좋은 하루.
