When I got home, I found a strange slender big-breasted gal! For some reason, she stayed there and gently seduced me...

When he returned to the house where he lived alone, he found a strange woman there. Her name is "Sarina". He doesn't talk about himself, and no matter how much you ask him, he insists that he's not going home. Even though I'm confused, for some reason I feel at ease when I'm with her. That's how their ``strange communal life'' began. ``Sarina'' is beautiful and somehow has a dark side. They gradually become attracted to each other, and eventually become one. It was like a dream-like life -- but one day, she suddenly disappeared. What was left behind was an empty room and memories that were too full. "I" start running to get back those irreplaceable days. I realized my true feelings for the first time after I lost them. Who on earth was “Sarina”?
