Ok i reread tge previous chapter ANDDD He controls his thumb nails length to not him

i’m pretty sure he only cuts them since he’s a half breed and i believe his brothers even mentioned it as a significant point since he spent a long time trying to grow them out and he cut them so that the mc could be more comfortable which is really cute

Actually I've read the next chapters and yess he cuts his nails only the right hand and keep his left hand nails
