Just like Black Scarlet, Airi had disappeared over the 17 years. However thanks to the information from Black, you found out that she was attending collage. Black also gave you the address to their new home but you had to swear on your life thst you would NOT tell ANYONE else about it.

On your way towards the home, you stopped a certain blonde hair beauty leaning against the rail; it was her, now being 23 years old.

Airi: "Mm? Oh, hi Y/N!"

(for those who met her in the previous book, I'm changing her age so that she wouldn't be too old in this)
