My only issue is either lulu learned Japanese culture quickly, or the author doesn't realize how different their culture is. Mainly regarding food and always shouting "delicious " after every bite. I would of liked introduction to Japanese culture , at least a couple pages

She had a month to study before meeting Ten, it's not a lot to learn everything about a culture, but Japan's day-to-day culture is very easy to access through media and such. And seeing how diligent Lulu is and how aware of her image can impact the opinion of humans about her people, it really isn't that weird.

I think this makes sense, also I bet Lulu learns fast as well.

I’m so curious if the other world mystery meat is even safe to eat? Maybe the Princess can eat human food fine cuz she’s super strong, but Ten is just a human.

Are there any diseases that exist on Lulu’s planet that’s already vaccinated for and stuff but can be deadly for people not protected? Is there new bacteria in the food that has the potential to make Ten sick? Is eating it raw even SAFE for a human

I’m pretty sure there’s cases where a whole group of people are wiped out because foreigners brought new diseases in— couldn’t that happen here? With the food especially.

On a less nit-picky note, I wonder what it tastes like? If food is prepared and plated to look pleasant on Lulu’s home planet too?

We have quite a few sci-fi stories that explore that, but in reality it's like a plant pathogen interacting with humans. It's not designed to affect us, so we don't get affected. A pathogen from a whole entirely different system of unrelated life would be astronomically low (pun fully intended). But also this is a fictional story so maybe we may see something like that.

Usually don't get affected.

I learned recently that tuberculosis started as a soil bacteria. Its ability to resist and take over predatory amoebae turned out to carry over to our macrophages. Oops!

As for real alien biology, I would give higher odds to the equivalent of bacteria and protists (seek out food in the environment and break it down) crossing over than to viruses (hijacking reproductive machinery).

But if there's some reason to converge on the same DNA and amino acids, or if panspermia seeded the same cellular biology everywhere, that would increase viral odds.

This love is massive.

you know what else is massive
