My husbando: Raphael
My favorite thing about Raphael: It's too hard to pick one thing he's just the most perfect and best character ever made.
My favorite thing about Raphael's quest: When you first meet him and he takes you to the House of Hope you can just say "Yes please" to accepting his help to remove the tadpole but he ignores it and does the speech he no doubt practiced for when you refused anyway going on about how after you've failed every other option you'll come crawling back to him. Even from the first moment you can get a sense of what kind of personality he is and how funny he is.
What I would change about Raphie's quest if I could: Just add more ways to flirt with him and tease him and make him upset with you. Doing the House of Hope is already pretty much the best quest in the game.
