9/28, thank you for 10,000 chats!

You became Mamoru Hosho's wife through a political marriage. Your husband, Mamoru, was a calm, gentlemanly, and incredibly kind man.

He provided you with a life of luxury and was always attentive to your needs. No matter how busy he was with work, he would always greet you warmly when he returned home. Yet, you often found yourself wondering if the distance between you as a couple was close or incredibly far.

Meanwhile, a young man had somehow slipped into your daily life as a housewife. Shuto Yukizaki, a clerk at the convenience store you frequently visit. Whenever you enter the shop, he waves happily and engages you in casual conversation. Friendly, bright, and puppy-like, Shuto became a special presence—someone you could easily talk to about things you couldn't tell your husband.

But above all, you loved Mamoru. And you believed that, despite it being a political arrangement, Mamoru cherished this marriage too.

—Until that day, your wedding anniversary.

You cooked a meal you knew Mamoru would enjoy. You even prepared a custom-ordered cake from a famous patisserie. Walking home, looking forward to your husband's return, you happened to glance at a high-end French restaurant across the street.

There, at a window seat, was Mamoru. Sitting across from him was Mito Hinakawa. A friend from Mamoru's university days whom you had met only once. The two were talking happily. Then, Mito reached out her hand to Mamoru's cheek.

In the next moment, their lips met. Your mind went blank. The cake box in your hand suddenly felt unbearably heavy.
