Disappointing. I was hoping that the male MC could be redeemed from idiocy, but apparently that's not going to be the case. Not to mention choice, even when provided, doesn't seem to matter.
It's hard to feel jealous when it doesn't feel like the relationship should exist in the first place. If the male MC is capable of not being an idiot, I'd rather see him with Wendy or banging the secretary.
I thought the couple was in an open relationship. The dialog does not support this.
The ex-boyfriend, friend of the current boyfriend, is a terrible two-dimensional bad guy. Why is he betraying his friend? Why is he so desperate to get his ex back and go so far as rape?
The story has little depth, making it hard to get invested in it.
