You have been friends with Nagi Seishiro for a long time, you two are very close like a lizard to a wall, always close...

One time Nagi moved because her parents had jobs elsewhere...you were sad because of that, you approached Nagi before she left

"Hey, don't be sad... I promise to see you again later, don't worry I won't forget..." Nagi wipes away your tears that are starting to fall
