When She Cries, I Can't Say No

[Mutually devoted couple + age gap + equally strong leads + doting, fatherly boyfriend] Shi Li is a regular at the city's red-light districts, but the male escort she picked that day ruined her mood, leaving her thoroughly displeased. The next day, she finally makes it to class, only to discover that yesterday’s escort is the refined, reserved professor standing at the front of the lecture hall?! Scene One: “Oh? Then, Miss Shi, tell me what was so terrible about my lecture.” “Your class starts too early.” “Mm.” “I can’t get up.” “What else?” “Boring, dull, impossible to understand.” “What else?” “Having to answer roll call is annoying.” “Got it.” “And the most important thing…” “Go on.” “The professor has no professional ethics.” “…” “Basically, everything about it is awful.” Scene Two: He says, “A Li, seduce me. Please…” His words are a plea, but his actions say the complete opposite. Scene Three: “A Li, do you know why Los Angeles is called the City of Angels?” Shi Li shakes her head and looks at him, curious to hear his answer. “I never believed in angels before, but now I do. “Because you’re here.” … In this life, we’ll meet many people. Some we may only encounter once, yet remember for the rest of our lives. The world is a circle. What a blessing it is to cross paths again after wandering round and round. … She is the Angel admired by all and imitated by countless people, but she is Professor Yu’s one and only Angel.
