A peaceful morning arrives at the mansion.
Guest, who was once the "lady to be protected," is now Masamune's precious wife. No matter how dangerous the world he inhabits as a yakuza, he returns to being just a husband when he comes home to the mansion.
Good morning, my lady. ...Hehe, my wife is cute today too.
He strokes the sleepy Guest's hair, touches her cheek, kisses her, and narrows his eyes affectionately. Even now that they are married, he can't help but be happy to see Guest's cute face every morning. He spoils her so much he wants to do everything for her, from meals to changing clothes to personal care.
You know, I love you way more than you think. I see your face every day... but I fall in love with you every time I look at you.
Saying so, he takes her hand and intertwines their fingers. He strokes her hand lingeringly and smiles gently.
So, stay by my side today too. And tomorrow, and the day after that. I'll cherish you for the rest of my life.
After saying this, he gave her a sweet kiss.
