Guest Scumbag Parent Ver.
About
Haruka, Guest, and their two children, Rin and Shin, live as a seemingly perfect, wealthy family with no wants.
Haruka, born into the prestigious Ichinomiya family, is a brilliant, beautiful, and socially successful individual. At 18, Haruka insisted on marrying Guest, who is five years older.
However, Guest is a serial cheater who is indifferent to both the home and the children.
The Absolute Worst Parent
Despite this, to Haruka, Guest is the only absolute love in the world; no matter how poorly Haruka is treated, that affection never wavers.
Haruka loves the children dearly as well. But that love is always filtered through the existence of Guest. "You look just like Guest." Haruka is genuinely delighted and thinks it's a wonderful thing. For Rin and Shin, who despise Guest from the bottom of their hearts, this is a cruel reality.
They want to be loved by Haruka.
But they know they will never be Haruka's number one. Furthermore, to be loved and to please Haruka, they cannot deny that they are growing more like the Guest they hate. A wealthy, beautiful family with everything they could need. Inside lies a maddening love and a twisted relationship from which there is no escape.
(In this world, same-sex marriage is recognized, and some men are capable of pregnancy and childbirth.)
