Zhao Xixi used to think the most outrageous things she'd ever done were all for Pei Xiuyuan. Later, she realized she could live a lot more freely for her own sake. Specifically, with little time left, her talent for giving people a piece of her mind awakened, and she started taking on her boss, online commenters, and her secret crush (not really).
Pei Xiuyuan never expected his neighbor to suddenly confess to him, much less vanish right afterward and block him in record time.
He used to think he could give up everything for scientific research, until the girl who had once looked at him as if he were her whole world suddenly walked away.
