That Niel guy still seems suspicious (like why is he so dedicated to the princess, no matter how she behaves?) but the height joke cracked me up. "If you mess up once..." lol
I will probably be like villager n° 24 if I get reincarnated most probably will take care of my body and use my knowledge of math and science (not much really) to get a good work. if I get transported with my own body I'm fuck.
If I'm isekai'd, I hope I can use many kinds of magic so that I can became a hermit somewhere undisturbed and will only choose to meet other humans when I want to so that I actually won't forget how to speak or something lol.
