I know a lot of people hate NTR. However, the part I like is the slow, steady seduction of the female character. In NTR, the girl often knows her seducer is poison, but she slowly lets herself be taken anyway. In that respect, Triangle Blue does not disappoint. This is also kind of the way the world works too. I've seen lots of girls who forsake the "nice guy" for total assholes. As one girl once told me: "A bad ass makes a girl's heart beat faster." In this one, the main character (Asato) was a total clueless cuck.A few people are confused why Akane is acting the way she is, but it revealed that Asato failed to get it up when they tried to have sex one time. Subsequently, it seems as if he either has a low sex drive and/or finishes very quickly. Asato also seems to ignore Akane's totally hot sister next door who wants him too. Any normal guy would have maneuvered tthem all into a threesome by now, but not Asato. In fact, after seeing how his GF got betrayed him, he immediately forgave her. He is a world class cuck who deserves what he gets.

By the end of the series, it is clear that Akane is just using Asato as a meal ticket and needs to get her sexual pleasures elsewhere. Unfortunately, the teen ager who is satisfying her & her hot sister (lucky bastard) is also recording her and making $$ selling the videos on the Internet. In a way, this is satisfying as just about all the characters get what they deserve. Oh, well.
