Lol I think it's okay to think a drawing is cute. XD (I think Silver's drawing for HGSS is so cute!) It's not weird, because you like that personality the character has. Which means you would like a person who acts like that in real life.
Pokemon characters who I think are totally cute: (Original GSC) Ash, Gary, Morty, Eusine, Lance, Will (from the E4 in GSC, not the sprite, the artwork), Silver, Steven (from RSE), Roark, Volkner, Gold (the new one! He's so cute!), Aaron (of the E4 in Sinnoh), FrLg Red (from SSBM. His character looks cute.)
I don't exactly have a crush on them, I just think they're cute. ^_^ But, I have written a good fan fic about a girl and Morty once.
