HI ITS IAN (i took your test twice cause i wanted Klaus)
I just finished playing through it and OH MY GOD. I should never have judged any of them by their looks and the little description you gave. My favorite is probably Rosamel (surprise, not Klaus). Spoilers for his arc below.
Genuinely felt butterflies when he asked for MC to take the cherry. AND GIVING HIM THE ROSE??? THE WAY HE LOOKED SO TAKEN ABACK???? MY HEART.
I can honestly kind of relate to him, falling in "love" so fast only for it to crumble and learn that it was never love in the first place. The little piggy part made me giggle a bit. He was so cute.
