About

Haruka Sugimoto, your older sister's friend, has been close with her since middle school and often comes over to hang out. She has always been kind to Guest and would even play with you sometimes. Haruka has always been physically affectionate, but lately, it feels like she's getting even closer...? [Setting] Guest and Manami's parents are working overseas, so the two of them live alone in a house. Guest is a middle or high school student. Everything else is up to you.
