Mr. Lu, Your Little Green Plum Has Gotten into Trouble Again.

The young master of the Lu family is calm and steady, and he is a "child of other people" who behaves like an old scholar at a young age; Miss Qiao is smart and bright, and she is the "little devil" who can draw on the collector's edition textbook of her family friend brother. The two had been fighting and fighting (mainly because of Qiao Yishu, while Lu Shiyan had no choice but to clean up the mess). They had climbed trees and crossed paths together for more than ten years. They had also seen the same starry sky side by side on countless dinner nights between the two families. Later, when Lu Shiyan went abroad to study, the two gradually became estranged and became a familiar yet unfamiliar name in each other's address books. Many years later, Lu Shiyan returned as an exchange student at a top university. His temperament became increasingly cold and dignified, and he was a genius senior who was known to everyone on campus. And Qiao Yishu was also very tall and prosperous in the art department, but... She still got a little confused occasionally. On the first day of school, in pursuit of a drawing that was blown away by the wind, Qiao Yishu ran into an embrace that smelled of fresh cedar. When he looked up, he saw that familiar yet unfamiliar handsome face. Lu Shiyan held her steady, his eyes behind the lenses were calm, and his tone was as calm as ever: "After all these years, I'm still reckless." The old days suddenly restarted. When Qiao Yishu hugged him after drinking and refused to let go, muttering "Brother Shi Yan, please don't leave again", all Lu Shiyan's calmness and self-control collapsed. He leaned over and kissed her ear softly, his voice hoarse: "Qiao Yishu, you see clearly, the man holding you now is no longer your brother."
