Both stories are the ultimate "Noona/Jiejie Romance" (older woman/younger man), where the guy has been pining for the girl since they were kids. The main similarity is the deep, long-term devotion from the male lead; whether Li Wu was supported by Cen Jin in the past or Lu Zheng An was the "little brother" from the neighborhood, they both grew up with her as their only goal.
Both dramas also feature a reunion after a long time apart. In both cases, the boy returns as a successful, grown-up professional who is ready to pursue the female lead, who at first doesn't see him as a romantic partner. While Cen Jin ignores his feelings and Lin Yang just sees a "cute kid," both men are incredibly persistent, using their sincerity and maturity to finally convince the older woman to give them a chance.

Both stories follow a similar "Good Girl x Bad Boy" dynamic where a sheltered but determined girl falls for a rugged "outsider" who is secretly a genius. Just like Zhu Yun in Lighter & Princess, Mu Mu finds herself drawn into the male lead's dangerous, messy world and refuses to leave his side.
Both guys have a "genius" side—Li Xun with programming and Zhao with racing—and both are struggling in a dark place until the female lead becomes their anchor. The plot in both dramas involves a painful separation and a "years later" reunion where the girl helps the guy take back his life and heal from his past.
