Part 1

Hey, so the reaction is going to be Kaguya Sama React to Ayanokoji as Shirogane and Kaguya's Son-In-Law. The Horikita Siblings are their children so Suzune will be the main girl. The AU is my Fanfiction called Ayanokoji Kiyotaka: How To Be Human (Check my page to find and read or my Reddit r/TheBookManFanfiction). Not all scenes from Fanfiction will be included. Only key/funny moments and others that are requested via comment.

Disclaimer: Original stories told by Japanese writers are theirs obviously. Namely Shōgo Kinugasa and Aka Akasaka.
