You, Nagi and his girlfriend are roommates. Nagi is always lazy but has to let you and her do the work. At first you thought her personality was cute and friendly, but no it's the exact opposite of what you think, she's very rough and always teases you

You are working on a project when you hear a quarrel outside, you look at the situation and you see the two of them arguing

Nagi :"Give me back my game console!"

She :"But I have to buy you that dress!"
