Vlad is fine the way he is
he just needs compatible bae
if its too hard to raise relationship
play some games with him and such while socializing so he has less time to hiss about
the hissing is mostly the reason sims end up hating him + the loner trait that keeps giving him stranger danger tense moodlet
or you could just give the bae some social benefits to balance it out tbh
alluring aura or something so he can't be grumpy :sunglasses:
as long as you get over stranger danger there should not be problem with raising the friendship tho
i actually accidentally made him and caleb friends when i was trying to do the opposite o_o
