Not your boyfriend, not human either.
Living together with sprites that suddenly materialize?
Just like freebies that come together with bottled drinks like phone straps and magnets, some products come together with healing sprites. They are known as Therapia.
Appearing as you open a capsule that comes together with the goods, they will soothe you when you use products connected with them.
The sprites will fulfill you, whether while they're soothing you or making your heart go pitter-patter, as you live together with them.
Fabric Softener Scenario 1
Voice: Tachibana Shinnosuke
You come out of the shower.
Therapia: Ah master, you're warmed up? I've wiped your shoes. I don't think they'll get out of shape. Once dry, they'll be as good as before. It doesn't look like the things you bought got wet either.
... That bath towel? Heehee, yesterday it was washed with fabric softener and dried with a good dose of sunshine. It feels good and fluffy, right?
... Does it smell good?
You nod your head.
