[ABO + male-male romance + reborn + school life]
Let's say this three times because it's important: this is a sweet romance! Sweet romance! Sweet romance! (There might be a tiny bit of angst.)
Lu Yan always thought Nan Yu was a timid, insecure little Omega who needed protecting.
Then Lu Yan was reborn ten years into the past. He only wanted to hurry up and protect Nan Yu, but discovered that the Nan Yu of ten years ago was completely different from the person he knew ten years later.
Who can tell him why his wife is this laid-back, impossibly cool guy, called Brother Yu by a bunch of underlings?
Apparently, this Alpha who can't stand anything also likes taking quirky Omegas as underlings.
To win his wife over, Lu Yan, an Alpha, made a decision that went against his ancestors' traditions.
He sprayed on a potion that made him seem like an Omega, put on round glasses, curled his hair, and donned a white shirt, disguising himself as Lu Yuan, an Omega who smelled like braised pork.
