Because there aren't many masc presenting omegas, if you get what I mean. They tend to be on the more feminine side. Tbh, his dad looks very feminine in the face. It's just his build. Meanwhile, Doyun (artistically intentional) didn't seem more feminine until he got with an alpha and had more omega traits.

I don't know why Taeha was shock to know that Dohyun is an omega when his parents is the same. XD
