The Longer My Sister Stays Single, the More Rewards I Get

“I... I didn't mean what I said when I confessed today. I was just joking. I hope you don't mind!”

Late at night, a girl of sixteen or seventeen silently stares at the message on her phone, then can't help but start screaming.

“Damn it!!!”

“What is going on??”

“Why does everyone who confesses to someone always come back within twenty-four hours to say it was a misunderstanding?!”

As she keeps screaming,

the boy in the attic listens to the System's notification with a delighted expression.

“Ding-dong! Your younger sister's single streak has increased by one day. You may draw a prize!”
