Currently being published as a book and adapted into a manga! 'New Yamazato Mato-kun…! W-will you… make me your wife…?' I was proposed to by the school's top beauty, Hanegawa Riko, and before I knew it, my newlywed life had begun. My adorable wife follows me around happily every day, never wanting to leave my side. She's perfect at all household chores, and her wife skills are maxed out. On top of that, she's an extreme caretaker. 'I built a fortune through investments so you can live a life of leisure. Use it as you like…!' Such excessive service has become a daily occurrence. Moreover, she's so cute, wagging her invisible tail when I praise her with just a 'That's amazing.' Yes, in front of me, Riko is like a small dog that loves its owner too much. However, I shouldn't be too full of myself. This is a contract marriage—. Riko isn't in love with me. —But when I asked her, 'Why do you serve me so much?', she puffed her cheeks and said, 'Mato-kun, you're too dense…' Eh… We did a contract marriage, right…? This is a love story of mutual unrequited love that starts from a zero-day marriage, filled with nothing but happiness. *Thank you for ranking 1st in the daily, weekly, and monthly rankings in the real-world romance genre!
