"Akane, I love you..."
" you too, Asato......"

Our relationship started after that.
After going out for 4 years and graduating from the university, we decided to live under the same roof.
I found a job at a publishing house. Akane enrolled at a vocational school as a step to realize her dream.

"My drawing with Asato's writing, let's make a book together. That's my dream."

Akane's smile, my most precious treasure. The thing I don't want to lose the most.
No matter how busy we become we trust each other. We love each other.

I always thought these days would last forever.
So, until that guy came...

The worst anime I have ever seen, by the way I just found this anime on YouTube and I watched the whole eps 1, so I watched eps to because of curiosity, the characters suck, especially the heroine, she is a fucking bitch, after the first bad guy was done, akane fucked another guy who just wanted to take pics so that he could get money,then that guy fucked akane's sister which made the story even worse , I'm spoiling this because this is the worst anime ever,I hate yandere and NTS,and the story sucks.

I will start this review by stating that this OAV is a netorare themed OAV. If you don't know what "netorare" is, It's a type of story where a person you love/is close to you is stolen from you. So the story is supposed to make you feel bad for the person who gets there lover taken away. If you don't like these kinds of hentais don't watch triangle blue. if you do go for it.
Now onto the actual review

Story: Being a Netorare hentai the plot/ scenerio is somewhat generic, but making these to lovers chase there dreams makes it so much more read more

This title here is the genre-defining piece for NTR. NTR for those of you who don't know stands for netorare which means cuckhold, and it's supposed to get a rise out of people (in more ways than one). Stay away from this if you're a vanilla watcher but definitely check this out if you're a fan of the genre or aren't turned off by it.

The best way to describe Triangle Blue or any NTR is like a trainwreck, you know it's awful but at the same time it's so shocking you can't look away. That's the way it is with this title. Enter Sawamura, read more

This was terrible. The only one I could feel sorry for in the end was the main male protag. I'm not going to spoil anything but seriously, I really felt sorry for Asato(main male). His stupid gf hadnt changed at all, and even her sister became a dissappointment in the end. The female lead's sister was an anchor of sensibility and virtue, but even she became manipulated and turned in the end. The experience of watching this made me want to turn into someone who has no chance of ending up like Asato. If a gf cheats once and I find out, we're done instantly read more
