Professor Lu's Rules of Love

Every student at Lin University knows that Lu Zhaoyu, an associate professor in the Department of Mathematics, not only has a handsome face, but is also an excellent lecturer. He is serious by nature and rigorous in his scholarship. Everyone sighs: A flower on a high mountain is impossible to pluck. This post about Professor Lu has been pinned to Lin University's online forum for years.

Then, one day, a user named "Mu Shutan" posted a new comment on floor 25,000: He not only cooks a mean meal, but also knows how to say all the right things. He knows how to coax me and how to cherish me. He always says, "To him, I am a treasure he found by sheer luck."

The forum users were astonished, and began discussing it on floor 25,001. That went on until one sharp-eyed user noticed that a user named "LZY" had replied to floor 25,000 one minute earlier: "Good girl, come home for dinner."

The forum users: "LZY means Lu Zhaoyu?" "Is that really Professor Lu?" "Is that the professor's wife?" "Professor's wife, who on earth are you, to have actually plucked that flower on the high mountain?" "My Professor Lu (_)" "Who is Mu Shutan?" "@Mu Shutan, please teach us the essential rules for pursuing Professor Lu!" ... In no time, countless replies flooded in, and the comment section exploded.

Miss Shu Jin blushed slightly as she put down her phone. She pressed her lips together and glanced at the man placing sweet-and-sour spare ribs in her bowl, thinking: I wasn't the one who pursued him!
