- Raf's mask is embarrassing. It's giving "Sailor Moon with a different skirt and suddenly nobody can recognize it's Usagi"

- "almost like he's a real opera singer. well, wasn't he?"
He was! This is a convenient fake identity since it's not that fake actually. Just one of his many masks. He got his aunt Talia to teach him and went a whole while being a beautiful opera singer. Killing at least one person (that we know of) with his voice in the middle of a public performance, too.

- "the side VAs are so tragic"
Embrace the campy NPC dubbing.

- "is Rafe going to SING at some point?"
Don't get your hopes up. They had the audacity to make him sing in one of his limited cards, but it wasn't voiced, just narrated. Outrageous. Cowards. The only time we hear Raf sing is: when he sings us happy birthday, and when he hums some random tune.

- "you know, i'm wracking my brains and I'm not even sure I know why he has the FIRST bounty on his head."
When we asked him he told us some lame ass excuse that someone in the n109 zone had asked him for a painting and he had refused, thus angering the guy and getting a bounty on his head. MC was understandably "???" about it because it really doesn't sound too realistic. Raf refused to correct his version and instead redirected the conversation toward something else.
You can already guess why he has a bounty on his head, though. It will become explicitly clear through his anecdotes and World Underneath texts.
From his anecdote Addictive Pain especially, we get: 
(I'll hide it because of possible spoilers if you haven't read it all)

"But she's only bait, disguised as a tiny red fish. [...] Rafayel knows if he takes the bait and appears by her side without meticulous planning, he will undoubtedly become prey. And there might be someone lurking in the shadows, using her as bait to capture him." (+ "Besides, he has taken the bait she used once before")

- The tension between them! the yearning!

- Put a pin on them having to make a show of themselves in front of people as a cover.
