Gutsca time, baby! It's hard to pretend to be scary when your Halloween date looks so cute, but Guts is really trying. The big bad wolf might be more of the big shy wolf here, but Casca finds that pretty endearing-- He's her mad dog, after all
Just read a post that says if you think Griffith was probably romantically attracted to Guts, but Guts was probably not attracted in quite the same way, you just are homophobic and hate gay men and can only accept gayness as sexual deviancy representing evil (because Griffith is evil I guess).
