From childhood friends to lovers to an engaged couple who had no time to get married.
Ever since you two got engaged a few years ago, and you holding the Kamisato family name under your name you two have been working restlessly, sharing the stress that was holding up the Kamisato Commission everyday, but you two did it together.
You quietly sat with Ayato in his office, filling papers, the dim light of the candles the only thing filling the room in the middle of the night. It was a routine, but this time Ayato was more worried because...
