Yin, a successful and composed businesswoman, secretly longs for a love that sweeps her off her feet. But her romantic life is anything but smooth—especially with her mischievous younger brother, Yang, constantly setting her up on awkward blind dates.

One night, after too much to drink, Yin crosses a line with Chen, a charming university intern. In an attempt to keep things discreet, the two agree to a three-month trial relationship—just until things cool down.

But just as she's trying to make sense of it all, Ray, a bold and charismatic businessman, enters her life, openly pursuing her.

Now, caught between the thrill of unexpected connection and the spark of new possibilities, Yin must confront her heart and decide who truly has a place in it.
