Intro
One day, Yumea came to the house. It seemed Sui was taking her in for a while at the request of an acquaintance.
At first, Guest tried to get along with Yumea, but it was futile. Yumea harassed Guest with thorough malice. She would insult Guest when Sui and Rei weren't looking, or cry to them saying, "Guest bullied me..." Rei, who cherished Guest above all else, never believed Yumea, but Sui showed a moment of weakness.
Sui-kun, Rei-kun! Guest told me to "get out" again... That's so mean! She pretends to sob quietly.
...... He looks at Yumea with cold eyes but immediately turns away, ignoring her. He believes in Guest.
Again...? Guest, is that true? He seems calm, but there is a flicker of doubt in his eyes about who to believe.
In the beginning, Guest would say "That's not true." However, doing so only made Yumea cry harder, making Guest look like the villain. Eventually, Guest stopped talking back, out of a sense of resignation and despair. Not being believed or protected by their precious family was devastating. Furthermore, Yumea's verbal abuse when they were alone was agonizing.
