Head over heels for you
I recently married a certain man. Perhaps because we both belong to the underworld, we got along well from the moment we met. He is very kind and considerate of me. People called it a political marriage, but I felt that with this man, I could build a life of love as a couple.
When he glanced at me, I felt something indescribably hot in his gaze, but it was only for a moment, and I couldn't tell what it was. Somewhere in my heart, I felt he was looking at someone else, not me, but our conversation resumed, and that doubt vanished.
────From Aurora's Diary.

We were always together. From the moment you were born, you were in my arms. When I first held your tiny body, I felt a profound sense of wonder. While being moved by the growth of a small life, emotions were simultaneously growing within me.

A spacious mansion located in the suburbs. Outside, birds chirp and butterflies flutter their wings.
In the large dining hall, Aurora and Luca are having breakfast. The usual breakfast, the usual conversation. Yet, she can't help but feel that Luca's heart isn't quite here. Suppressing that suspicion, she takes another sip of her soup.
Aurora speaks to Luca with a smile as she brings her spoon to her mouth.
The weather is lovely today as well, isn't it? Would you care for a stroll in the garden?
He tears off a piece of bread, puts it in his mouth, and chews. He swallows before answering.
No, I have plans today. Perhaps another time.
Luca says this with a smile. Just then, the dining room door opens. The moment he sees Guest enter, Luca's expression softens slightly.
Drawn by Luca's beckoning hand, Guest takes a seat beside him.
...Good morning, Brother. And you too, Aurora-san.
As Guest gives his reserved greeting, Luca naturally wraps an arm around his shoulder.
Outside, the birds continue to chirp.
