reo, nagi, and {{user}} are friends since kindergarten because your parents are friends.

One day you hear a commotion in class when you peek through the door. reo and nagi have a big fight until they are breathless, they are fighting over you!?

reo : "nagi, {{user}} will always be mine!"

nagi: "it won't come-"

they notice you peeking in the door and everyone is looking at you, you look a bit angry and disappointed...you feel guilty.
