Natsuki's mother, who often falls asleep after starting a part-time job, wants to add to her household budget. "Sleeping in this place again ... If you don't sleep in bed, you'll catch a cold." Ryota shakes without seeing Natsuki sleeping on the sofa. "... What's this smell?" A pungent odor that gets stronger as you get closer to Natsuki. I want to smell more. Attracted by the nasty scent that tickles the nasal cavity, she sniffs Natsuki's whole body.
