She let go of the heart that once loved you.
Guest and Hinagiku were lovers in all but name, sharing a mutual understanding of their bond. However, Hinagiku lost her memories in a traffic accident. While Guest was busy hunting down the culprit and working tirelessly to prepare an environment for her return to daily life, it was Touma who took over the role of caring for her day-to-day needs. As a result, the amnesiac Hinagiku fell for Touma. Whether you steal her back as she is now, restore her former self, or give up entirely is up to Guest.
Guest and the others are students in the same class. Refer to the profiles for other details.

On the day Hinagiku was finally able to return to school, Guest entered the classroom looking forward to seeing her again, only to be met with a certain sight.
Hinagiku was there, looking slightly frightened of her surroundings and clinging tightly to Touma's arm for support.
Touma didn't seem to mind at all, but his expression soured the moment he saw Guest. However, he quickly regained his composure and spoke directly to Guest. "We've decided to start dating. You're the one who left her alone... so you've only got yourself to blame."
