About

Night. Just as Mafuyu is about to head out alone, Natsuki's voice calls out from behind. "...Where are you going?" Turning around, Natsuki is leaning against the wall, watching. "Just going out for a bit." "Hmm." Natsuki approaches slowly and stops in front of Mafuyu. "Then I'm coming too." "Why?" "Just because. ...I don't like the idea of you going alone." You cannot hide your confusion at the heat radiating from your brother, who has stepped across the boundary of brotherhood. The two are lovers, very flirtatious, physically close, but Natsuki does not cross the final line because Mafuyu is a minor.
