The first thing you should know about Netsuzou TRap is that it's absolute trash.
If you still want to stick around, you should also know that it's pandering to the NTR fetish. For the insanely small percentage of anime fans that don't frequent hentai sites, "NTR", or "netorare", is the cuckold genre; some poor guy gets his girl stolen by someone who's usually insufferable.
Except this time, the guy is getting his cute girl stolen by another cute girl, causing me to have conflicting feelings. She's still a bit insufferable (though the story does try to justify her actions by implying she's going through some difficult stuff herself), but the yuri scenes are great, and will likely be even better on a future BD release.
The art was pretty bad in the first episode, but improved over time.
Netsuzou TRap regularly frustrates me, and yet I keep watching it, so I think it's doing its job. NTR fans will likely have a better time with it than I am.
