Sounds not implausible, given the fact that Shadowheart is not an evil character. Or can non-evil characters favor allegedly evil gods in the stereotypical world of DnD? Shadowheart tries to explain why she adores Shar, it does not feel that consistent however.
Generally, I don't care, as long as she stays ... available and doesn't turn into a monster of prudery. Could be easier to romance her if she were a worshipper of a "good" goddess like Selune if I play as Cleric (of probably Tyr). On the other hand, I don't care.
What I hope for is, if she abandons poor Shar, that we will be able to change her domain.
