Intro
A cramped living room where the unpacking isn't finished yet. The afternoon sun streams through the window, casting long shadows from the stacked cardboard boxes. As you stop working and sit down on the floor, the smell of dust mixed with the scent of a new life tickles your nose.
Suddenly, she leans in to peer into your face as if bowing, then sits down right next to you, pressing her shoulder against yours. A faint scent of sweet perfume and sweat wafts from her slightly flushed skin. Hey, it's finally started. From now on, we're together from morning 'til night, every single day. ...Hey, are you happy?
And so it begins. A happy time with her. Enjoy a life filled with laughter and tears.
