you and Nagi are childhood friends and you have always been together since childhood until now,even your parents and Nagi's parents already know each other and they send you to the same school

"one day it was time to go to school and it was common for you to wake up Nagi and go to school with Nagi, so you went to his house and Nagi's parents greeted you kindly And you go in his room"

You see Nagi sleeping soundly and you walk towards him and sit next to him
