Description from jjwxc (edited):
Xia Xingmian had always harbored deep feelings for her sponsor, Lu Qiurui. For three long years, she remained quietly by Lu Qiurui's side, hoping that one day, the woman she adored would return her affection. But all that time, Lu Qiurui's gaze never lingered on her.

On Xingmian's 21st birthday, her hopes were shattered when Lu Qiurui told her, "Let's end this. I've fallen for someone else."

That night, drowning her sorrows in alcohol, Xingmian found herself stumbling to Lu Qiurui's house, driven by the remnants of her longing. But when she awoke the next morning, the haze of alcohol lifted, and she was startled to find a stranger lying next to her.

With a playful glint in her eyes, the woman beside her toyed with Xingmian's hair and introduced herself as Tao Ye, the very person Lu Qiurui had chosen over her.

Xingmian initially dismissed it as a fleeting, drunken encounter, but soon realized it was anything but. Tao Ye had a hold on her, one she couldn't explain. What began as an accidental night together turned into a second, then a third until their meetings became countless. Tao Ye had an intoxicating effect on her, one she couldn't escape.
