Thanks for the chapters, but i believe there are some misunderstanding in the translation part, i would like to share my opinion as someone who had read the webnovel,
First, all of countries' names are the same with the royal family who govern it, in mc's case it was 'フロィト froito', well, i too dont know what it will be in english,
Second, mc's country is a country which prosper trhough agricultural and greenery, both the princesses' names are taken from flowers 'Amaryllis' and 'Dahlia', so mc's nickname would be either 'ryllis', 'lilis', or 'ryrys/riris',
Thanks for your hard work,
I'm cheering on you,
