Yeonha is unsatisfied

After leaving behind her workaholic life—so busy she never had a moment to breathe—Baek Yeonha is finally free with her retirement. Despite exercising regularly and taking time to rest, she suffers from insomnia every night and can’t fall asleep. And the one who manages to lull her to sleep is Ju Seongbin, the boy next door—six years younger—whom she’s known since they were kids. But that brat who used to seem like nothing but a child… “Noona, I like you.” …confesses his feelings. “Noona, you can’t stop thinking about me, can you?” He was supposed to be just a close younger brother, but… since when did she start seeing him as a man? The heart-racing devotion of a younger man who has eyes only for Yeonha and comes on strong, gently soothing the wounds of a Yeonha who can’t sleep. “From now on, I’ll help you. So you can fall asleep, noona.”
