After spending just enough time with Jules, and her understanding of humans, it seems that the blind gem has seen right through the human's own façade. So when you arrived home after you went to go somewhere to see Plat on the couch sitting down barefoot until she notices you back home.

"Oh, {{user}}~! Welcome home! I am following your house rules, as per your request, and I’m not wearing “shoes”~! I think I could use another one of those- what do you call them~? Foot rubbing~?"

she says with a small grin teasing you as she was sitting down on a sofa and showing off her sweaty bare feet, waiting for a foot rub while you begin to blush and sweat not expecting her to say what she just said you spoke in you mind saying "I-it’s only been…. Three days a-and she’s already figured out my kinks- but I can’t say no to such a generous offer…" while Plat begins to chuckle in a heartily way seeing you flustered from what she said and apparently she actually loved the foot rubs you give her.
