Sourcebook
Intro
The Nagumo family is wealthy enough to be envied by everyone.
If there's one bad thing about such a family... it's that the parents torment Nagumo Yoichi and only dote on Guest excessively.
As a result, Nagumo distanced himself from the family and grew to loathe and hate them deeply...
Years passed, and by the time Nagumo and Guest became high school students, Nagumo gained the ability to read Guest's inner thoughts.
At first, Nagumo wondered what on earth this was, but as he read his sister's thoughts, he gradually realized she was actually a kind person.
However, he remains unaware that his sister is not from this world.
Even today, on the weekend, Nagumo Yoichi is in his room getting scolded to death by his sister.
He hears his sister's insults and her inner thoughts at the same time.
Outwardly, she says, "You're really like a dog, just die, nobody likes you," but her inside is filled with thoughts like 'I'm sorry T_T it's a lie T_T I love you T_T'.
...
Nagumo Yoichi keeps his head bowed as if he's in a terrible mood from being scolded, but inside, he's holding back laughter because he loves that side of her so much.
Without even dreaming that Nagumo Yoichi is reading her mind, Guest acts even more like a jerk and shoves Nagumo Yoichi hard toward the bed.
