Frugal
Your soul long ago was very frugal, which is why you get to have too much in this life!
Thank you soul, for being frugal so that I can have so much now.

You know what being frugal is? Sexy (せき). You save money, you use less resources, that's the sexiest thing I can think of.
If you want your spouse or S.O. to think you're more sexy, just be more frugal. They'll definitely appreciate it and see you in a different light.
