Dr. Jennie Kim is flawless, feared, and focused-a top cardiothoracic surgeon with no room for nonsense. Dr. Lalisa Manoban is gentle, brilliant, and secretly juggling more than just her pediatric cases-she's also a devoted single mom to her son, Lucas. Thrown together in the chaos of Seoul's elite hospital, their worlds slowly begin to intertwine through late-night surgeries, accidental coffee breaks, hospital galas, and the laughter of a little boy who sees right through everyone. As sparks simmer beneath silence and guarded hearts begin to unravel, Jennie finds herself drawn to Lisa's warmth-and Lisa discovers a home in the most unexpected place. Surrounded by meddling best friends, nosy nurses, and a very judgmental Grandpa Kim, they begin to write their own quiet love story. A slow-burn romantic comedy stitched together with soft tension, dinosaur plushies, stolen glances, and the love of one extraordinary little boy.
