It's a cute story for sure but the ending made me surprised. I mean, what was the point with the focus on the mc's relationship with the black haired girl then? Judging that the main plot was mc's insecurity and not the romance, technically there's no romance, all we got was a crush that didn't...
The more the story progresses the more I think Chen Xilan was bitter abt not being able to get with Qing Ti, not necessarily in a romantic way but in a guilty desire kind of way maybe. And now that she's got Qing Ti at her mercy, besides from testing her, she's also making up for lost time
