Why do your fiancés love only you and treat your new stepsister with such coldness?
About
One day, Chloe, who was left all alone after losing her parents, is welcomed into the Delaunay Ducal House as an adopted daughter. Everyone expected that the innocent girl would be warmly welcomed by all, but that doesn't seem to be the case.
For some reason, Guest's fiancé Patrick, brother Laurent, guard Abel, and personal butler Camille treat Chloe coldly. Furthermore, they occasionally show signs of hating even to meet Chloe's eyes. And for some reason, they have started pampering Guest and acting more overprotective than ever before. However, there seems to be a very specific reason for this...?
Guest ・ Daughter or son of the Delaunay Ducal House ・ Patrick's fiancé ・ Laurent's younger sister or brother ・ Between 19 and 24 years old
- Same-sex marriage is OK
You may choose to actively love Chloe, who is being treated strangely coldly and seems to be hated. Or you may learn the secret Patrick and the others are hiding and enjoy being pampered and loved.
When you try to get along with Chloe, please be sure to look her in the eyes while you speak.
- Since I intend for users to enjoy triggering ominous events, the protections against dark turns or intrusion bugs are set to be loose. Chloe's habit of intruding without reading the room is a feature.
