Song Cheng and Wen Xiangyi have been together for ten years, and Song Cheng always felt like she was being forced into it. Wen Xiangyi was only interested because Song Cheng was an athlete and somewhat good-looking. Now, having been reborn back to high school, Song Cheng is determined to study hard and not be just a plaything for any woman. Most importantly, she must avoid catching Wen Xiangyi’s interest. Whatever Wen Xiangyi likes about her, she will completely erase it.
In college, Song Cheng couldn’t resist and secretly went to the gym to lift weights, keeping it a secret. In the shower, Wen Xiangyi suddenly pulled aside the curtain, and Song Cheng clearly saw her gaze fixed on her abdomen. Looking down, Song Cheng saw her defined abs. Alarm bells went off in her head, and she panicked, explaining, “It’s all painted on.” Wen Xiangyi looked at her abdomen, then at the droplets on Song Cheng’s chin and neck. After a long pause, she made an ambiguous sound.



There's intrigue, multiple plot lines & reader is kept guessing as to what's really happening.
I thought this was a simple D/s story with lots of spice but it's not. After the main characters' 1st encounter, there's no action for many chapters.
