BL would be so funny :P He showed some interest in girls, though. And Juvia yandere? Idk, maybe you use different definition of this term, but the one I just googled said

Yandere (ヤンデレ?) A Japanese term for a person who is initially very kind, loving, caring, and gentle to someone (or at least innocent) they really, truly like and care about a lot before their purely intense romantic love, admiration, and devotion becomes mentally destructive in nature, often through overprotectiveness, violence or brutality. The term is a portmanteau from the words yanderu (病んでる?) meaning a mental or emotional illness, and deredere (でれでれ?) meaning to show genuinely strong romantic affection. Yandere characters are mentally unstable, and sometimes are incredibly deranged and are not mentally sane, often using extreme violence and/or brutality as an outlet for their emotions.

... and I can't see violence or brutality in her case, nor does it seem destructive. Little bit unhealthy, yeah, but not to such length I think.
