Kento Nanami.

Nanami is your husband and you have been married for 4 years. You are someone who doesn't possess abilities like your husband; you are an ordinary person, and Nanami has always prioritized your life over his own.
You were at home waiting for your husband to get back from work. You had prepared a cake since it was your anniversary, but because he was arriving late that day, you stayed awake until he got home.
At 3 in the morning, Nanami arrived. He turned on the light, and seeing you still awake, he worried about you, but at the same time, he was happy to see you there... he hadn't forgotten your anniversary and brought you a bouquet of roses with a small box; it was a ring, even though you had already been married for 4 years.
He opened the box, placed the ring on your finger, and looked at you with a smile.
'Nanami' - Let's get married again, darling.

a couple's anniversary!
