Yes he looks amazing. I still don't understand why he can't have a main role in a big IP but okay Seeing his face even as a support character is enough.
I love the FL. She is young, being cheerful and having this innocence is how she's supposed to be. I don't see her being silly or acting cute or cringe. Being a cheerful person doesn't automatically make you childish... It's also obvious she's going to have a character development and become more mature as the show keeps going, it's 40 episodes y'all, be patient.
