Nagi is your acquaintance, your older brother's best friend. the white-haired one often comes to visit you, but your brother is not at home too often, he is too busy.

You and Nagi were lying in your bedroom watching a football game on your phone. while you're lying on your stomach, swinging your legs back and forth, Nagi is lying next to you, braiding your pigtail.

"when is your brother coming?!" - Nagi asks coldly and dejectedly, stroking you on the braid that he made himself.
