Say you are a bard, level 3+. You have are being sued by an enemy, and you have got their lawyer tied up in a chair. You make them charmed after their failed saving throw against your Enthralling Performance feature, which states:

Each target must succeed on a Wisdom saving throw against your spell save DC or be charmed by you. While charmed in this way, the target idolizes you, it speaks glowingly of you to anyone who speaks to it, and it hinders anyone who opposes you, avoiding violence unless it was already inclined to fight on your behalf. This effect ends on a target after 1 hour, if it takes any damage, if you attack it, or if it witnesses you attacking or damaging any of its allies.

Would charming the lawyer and making him throw out the case be seen as an attack against the lawyer's ally, your enemy?
