【Arctic Firefly】I can’t believe that the student council president became everyone’s big sister and gave H services to all the male students (younger brother)!

[synopsis]
The story is about a girl who becomes the big sister of the entire student body through the scheming of her own brother.
It’s a great way to get to know your fellow students and get to know them better.
Feeling responsible, the older sister, the student body president, tries to convince her younger brother to renege on his pledge, but he says it’s impossible.

In the event that you’ve got a lot of money, you’ll be able to take advantage of it.

In the event that you’re not able to get a good deal, you’ll be able to’t get a good deal.
