In my Haikyuu omegaverse, Suga is raised by his somewhat traditional omega mother. She’s traditional in a sense that whenever Suga has to talk to an alpha, she makes sure she’s around or another bonded adult is around. That was the practice before. Suga doesn’t tell his mom that most of the members in the volleyball team are alphas, and Takeda sensei and Coach Ukai who are adults, are around most of the time anyway. So when Daichi, a modern day alpha, asks Suga out; Suga just looks at him confused and says ‘but aren’t our parents supposed to agree on the courtship first?’ After that, Daichi spends an entire night researching on traditional alpha/omega courtship, because not only is he trying to impress Suga but also Suga’s mom.
