[Age gap + older man + sweet and angsty + university teacher and student]
There are hints of star-crossed bitterness at first, but the sweetness starts to emerge in secret as the story goes on.
Twenty-three-year-old An Wenlan has two secrets: she has hated Cui Zhixing for ten years, yet during the days they spend investigating a case together, she falls in love with the man she ought to hate with all her heart.
Forty-one-year-old Cui Zhixing is composed, refined, calm, and professional. Ever since she was six, he has stood in the shadows, never leaving her side. Yet all he says is, “You should call me Uncle.”

The assistant: “?” I wish you both happiness.
