Riley is apparently the Adventurer ISFP-T. My first character that's one of the yellow personality types. But I figured he would end up being pretty different from the character's I've had so far.
Melissa is an ENFJ-A, which makes sense, since she and Andrew have a lot in common. Despite both having really tragic lives, they have really positive outlooks on life, and choose to be happy rather than depressed.
Emelia is an ISTJ-A, which I can see, because she's like the dark mirror of Jinho in a lot of ways in her interaction with Alicia. Jinho knows a lot and uses it to build Andrew up in the areas where he's ignorant and uses his sensible nature to be strong for the both of them, while Emelia uses her logical nature to be demeaning and tear Alicia down for being emotional.
