Like the world building, but honestly everything else is bad especially the Romance.
Red hair, family of the biggest aristocracy. She must get a lot of suitors as well as compliments. One word from MC however and she becomes harem member.
Half-elf, has been disdained but has a kind character and desire to socialize. One Pat and all her trauma fades into affection.
It does not work that way. I’m not a love expert but I can tell this is bad love advise.
