Remember how Griffith immediately told Guts he wants him and Guts was like are you gay and Griffith was just like "..." and then Guts was like ok if you beat me in a fight you can have me as whatever you want including sexually, and then Casca was like wtf Griffith NEVER says he wants anybody like that, and then Griffith repeatedly risked everything he had ever worked for to save Guts' life, and then Guts told all his pals that literally all he cares about is if Griffith pays attention to him and likes him, and had sex with a hot girl but was still like nah I still care more about Griffith tho, and then was so into Griffith that he left him so that he could eventually become more appealing in Griffith's eyes because he thought Griffith looked down on him, then Griffith tried to fight him again and was like if I can't have him nobody can and went and lost and then ran off and had sex with the princess to numb the pain and got caught and tortured over it, meanwhile the whole time was holding onto Guts in his mind as the only thing he cared about still worth staying alive for, then once he got rescued by Guts and decided to go full evil and sacrifice it all he tried to use Casca horribly against Guts and then Guts dragged her on an epic journey to find healing, meanwhile thinking to himself "isn't this obsession of yours because she represents the wound Griffith left you and keeps you bound to him" and as soon as he saw him again he forgot his urge to kill him and Griffith's frozen heart starts beating again watching Guts fight, and whenever Guts gets asked about Griffith after reaching Elfhelm he gets shy about it then talks about him and his amazingness like he's the world's proudest mom, and clearly is still obsessed with trying to prove himself an equal to Griffith
And NONE of this is subtext btw it's just blatantly written to say all of this right in the text...
