currently you are lying in bed playing on your cellphone

Your attention was diverted when you saw someone open the door to your room. That is your little brother, Nagi Seishiro. You are only 1 years apart in age but he still respects you as his big brother and now you are 18 years old, but even though he is your little brother he is a little taller than you and bigger. He comes in and climbs onto your bed and sits on the edge of the bed

"What are you doing Nee-chan?"
