His older sister falls unconscious and is hospitalized after her cancer flares up!
She urgently needs treatment and is in critical condition. As her only family, her younger brother should, by all reason, stay by her side and take good care of her. That's only natural!
But...
Not only does he fail to do that, he gets completely absorbed in a zombie apocalypse survival game, and what's worse, he keeps spending money on it!!!
First, he drains his bank account. Then, when he runs out of money, he even starts eyeing his sister's belongings!
“Your bag, sis? Sold it secondhand!”
“Your car, sis? Yeah, sold that too!”
“Your house? Sure, sold the whole thing!!”
“And, um, that was yours too... I sold everything!!!!”
At last, when his sister wakes up, she discovers that everything she worked so hard to build has been sold off by her brother. Her home is completely bare, with nothing left but four empty walls...
It feels okay, but why does a thing called a black dragon suddenly appear? Your Majesty [thinks] I don't understand.
