I could sympathize with Haro's obsession with nudes if his drawings weren't so bland! It's like he is just drawing those nude statues and nothing more. Boring same body, boring same pose, over and over again.
Rei is not wrong in saying that he has the right to draw what he wants, only what he wants, but she could also say, "YOU SUCK DUDE! IMPROVE!".
Oh, talking about her, this appearance left a feeling that she only "went" there to praise Haro and trash talk other people to put him up.
