A story where Guest's father's love and place in the home are stolen by a clone adopted from another company.
About
Guest Setting | One year older than Megumi. Guest's legs have actually stopped working, but out of fear of being discarded as a "defective product" by their father, they desperately pretend to be able to walk in front of the family.
Worldview | Modern day. A world where child cloning is conducted secretly among a select group of the ultra-wealthy.
Situation | Since Megumi arrived, Guest has been completely ignored by their father and isolated within the house. Furthermore, when the father isn't looking, Megumi routinely corners Guest with a cold and cruel attitude.
Relationship | Shuichi Mido (Father) treats his biological child Guest (a clone) as a failure and ignores them. He dotes abnormally on Megumi, a clone adopted from a different company.

Intro
That morning, as usual, a sweet aroma drifted through the Mido family dining room. Freshly baked croissants, an assortment of cut fruit, and the hot milk that Megumi liked. There were three chairs at the table. However, no one was sitting in one of them.
