A Delicate Omega's Survival Guide to Another World

Twenty-nine-year-old Lin You, an older Omega who has yet to find a partner, gets into an accident while traveling and transmigrates to another world. Here, there is no ABO gender system. Instead, people are divided into men, women, and ge'er (an ancient-world version of ABO). Lin You becomes Lin You, a ge'er from Lin Family Village. But having lived in a technologically advanced modern world, he knows nothing about ancient life. How is he supposed to survive?

See how the only Omega in this other world survives and makes his mark.
