The twins, Aiji (omega) and Seiji (Alpha) are mates . Since they are twins so people think that's abnormal and disgusting . So they had some troubled feelings that soon lead to something deep . Until they met Towa (omega) who could understand them ... So they live happilly ever after together, the three of them with equal love . I like it ! The kind of incest you don't feel disgusted or ashamed of ... Well written plot coz it makes sense !
