The world building is very refreshing! And the characters have depth in their personality. I feel relatable with the FL in terms of getting rejected and have to act as a replacement until the chosen one is free to get there. The ML so far is meh. Let's see how they justify his change of heart to our FL. Even if he recognizes our FL, and fall for her, he's still not a loyal person to change his heart from time to time like that.
