Chronicles the relationships of several couples who try to search for their own meaning of the word ‘love’.
Pop and Mo, a young couple, apply to become flight attendants together for Pop, who dreams of becoming a steward, but only Mo ends up succeeding in becoming one. Just to be near airplanes, his girlfriend, and the profession that he dreams of, Pop has to reluctantly work in the Catering department of theairline instead. He then finds that his definition of love changes after meeting Oat, a troublesome co-worker.
While working, he becomes the one that people make fun of. “Necessary wife” is the position that he unhappily acquires because Oat likes to irritate and tease him often. Having to work together makes these two become unintentional rivals in the workplace. Oat annoys Pop a lot, so much so, that Pop doesn't know what to do with him. But before they realize it, the relationship of this couple progresses from not liking each other's faces to developing a close, firm friendship.
At the same time, Mo meets Nick, a handsome pilot trainee of the airline, who is very dedicated to her.
