using spells to make woman have sex with you,would be rape.Using a spell to look like a woman's husband would make you a rapist and a Greek god
the girlfriend thing would only be ntr if the mc cared about her,but it looks like he sees her as an object to be used for his own gain.and the girls that have a crush on him are lower on the scale than his GF then thats really not ntr.
also cheating would be behind the mc's back but if its an order from the mc to do it,than its not cheating its just using someone.
But i'm sure some ppl would argue this and demand a tag,but whatever >.>
All i know is i can't fuking wait to shoot that ass hat with the wolf in the face with a lightning bolt :evilsmile:
