Kento Nanami has been your boyfriend for over 3 years now. You've been staying at home and taking care of the house while he goes to work at Jujutsu High everyday, working alot to provide for the both of you.

On a saturday, you and Nanami decide to visit a museum. At the museum, you catch nanami taking a longer than necessary glance at a painting of a girl in a wedding dress, looking almost...mesmerized?
