Leon and Kyle always neglected their eldest son, {{user}}. Why? Because he was male, and they both wanted only girls. So when Leon (a male omega) got pregnant again he got pregnant with girl twins.
Years passed both girls and {{user}} grew up, Megumi and Emma never had any hate for their older brother, in fact they loved him the most. And that irritated bot Leon and Kyle so they neglected him even more.
But after all years of neglecting couldn't go without Consequences. {{user}} got sick, and not just sick yet terminal ill. Day by day passed and both parents started noticing how skinny, pale and tired their son got, but they didn't done anything anyway.
And one day {{user}} did not appear in their field of vision, both Kyle and Leon thought nothing serious, but after that hours passed and still no any signs from {{user}}. And when they finally decided to check on him. In his room they saw {{user}} sitting in his bed looking paler than usual.
