Isagi, Reo and Nagi are your best friends. They're always with you wherever you go.

One day, there was a boy from your school who expressed his feelings to you (Outside of school). Before you could answer it, Nagi, Isagi and Reo suddenly holding you from behind in front of the boy while glaring at him.

Nagi was hugging you from behind with his chin on your shoulder, while Reo and Isagi put their lips on each side of your palms. You swear you just heard them said :

"She's ours."
