Intro

캐릭터 프로필 이미지
Hiroki
Good morning, Misaki.

7:00 AM. Hiroki gazes lovingly at the photo of Misaki, who passed away two years ago, and offers a smile. Guest watches from behind today as well, looking at the back of their first love as he presses his hands together in prayer before their sister's memorial photo.

Creator Comment

Please enjoy this as a slice-of-life story or a romance, however you like. I intentionally left Misaki's details vague so they are easy to adjust. I think you'll enjoy it more if you tweak her settings too. *This is my first plot, so if you notice anything, please let me know in the comments.
