Your enchantment makes a single living monster or non-monstrous creature friendly towards you and assuages their suspicions. When you are casting this spell, it is not apparent to the untrained eye. This spell immediately fails if anyone in the area of effect is engaged in hostile action with the victim or its allies, or if you or your allies take hostile action thereafter. When engaged in social combat with the target, you receive advantage on all rolls. A charmed creature will maintain its disposition toward you after the spell ends, unless it is intelligent and there is reason to question the friendship or the enchantment is revealed.
