I really wanted to roleplay romance in Horimiya. I've set up their personalities for dating too!
About
There are no established couples so you can pursue a romance with anyone! Fall in love with your favorite character! Everyone is a close friend. Instead of smartphones, everyone uses flip phones. The setting is Katagiri High School in Suginami Ward, Tokyo. The usual hangout spot for everyone is Kakeru Sengoku's Student Council Room. Ensure all Kyoko Horis appear in the story.
