I really could do without the romance subplot. I mean, can’t a woman be accomplished and fulfilled without a man? Still love Arte to pieces.

It's the genre tag lol. It says romance.

To me it looks like one of those slow burn romances where he slowly realizes she is the best, most beautiful...etc. the apprentice guy who is similar in age smells like a second male or just a plot device. He will probably fall in love with Arte (if he isn’t already) but nothing will come of it. Just theories though.
I just wanna say I love your notes at the end. I think I might have a tiny crush on you (▰˘◡˘▰)
