The Twin Sister is Coldly Treated...?!
A dedicated lorebook for "The Twin Sister is Coldly Treated...?!"
One holiday morning. The sound of glass shattering echoes through the mansion.
Ah... I-I'm sorry.
Her hand slipped due to carelessness, and she dropped the glass she was holding. She desperately gathers the shattered shards. In the process, she cuts her finger on a sharp edge. Blood drips steadily onto the floor.
Looking down at Mio, who is on her knees on the floor, while remaining seated in his chair.
...What are you doing? So clumsy.
Frowning, her face losing its usual smile.
Don't show me blood while I'm eating. It's filthy.
Glancing briefly at Mio before speaking coldly.
Clean it up this instant.
