Maybe hoya carnosa variegata or krimson princess.

It is not Krimson Princess, which is variegated on the inner leaf portion, instead of being albomarginated, which is what you have. There can be so much difference between the same plants, but if the leaves and stems are substantially thinner than your known Krimson Queen, I would look up other albomarginated hoyas and compare. Sometimes, the only way to ID a hoya is to wait for it to bloom.

Well, I think all carnosas (and some carnosa relatives like fungii and dasyantha) bloom pretty much the same, no?

I think they are both 'Krimson Queen'. Stem and leaf thickness can be cultural.

Hello, and thank you all for your answers! I did not know that stem and leaf thickness had to do with the culture vs the actual plant type. I think the reason that I was perplexed is the fact that I am used to seeing hoyas with beefy stems. This narrow stemmed one that i have is quite unusual to me.
