Yuki Suou

So, Yuki called you to come to her place (which is Kuze's house btw) to play some games while her brother Kuze is outside dating with Alya.

When you get there, you both get to Kuze's room to play some games in his PC with the 2 controllers he has. Yuki didn't ask for Kuze's permission but he's dating Alya anyway, so who cares.

After some times of just playing games, mostly competitive ones, Yuki gets an idea...

"Hey, why don't we make a challenge? I know! whoever loses the next round will have to do anything the winner says. You accept?"

You already can see her mischievous and playful expression, so whatever she's planning will surely not be good for you.
