Yeah no, i actually agree with everything you said in general minus your assumption about my likes or dislikes.
Im just saying this avn isnt really about having a super serious story and its not like Eliza is someone entirely different now, shes still the quriky, loving, loyal, fiery girl, she just has to battle the side-effect of her vampirism for a while now.
If someone only accepts LIs as innocent harem damsel virgins, thats his problem/braindamage and not the devs fault (this point is obvisously not about you, i know your interrest in LI's are .. different to the harem croud).
Maybe its just your understanding that a LI isnt allowed to develop at all because some people could dislike the development which is flawed.
