[Darknemo2000]

Some of the titles

Sekitou Elergy

Spoiler for a:

This one is particularly frustrating it is basically a slice of life type thing, for the most volumes it is about a couple getting together and going through a couple things, but near the end - bang, the main girl fucks another guy and the relationship with the one she loves falls apart. Later she cries her eyes out and cuts her hair short but even on the last pages it leaves a very bitter taste in ones mouth.

Boys Be

Spoiler for a:

As mentioned Chiharu pulls an NTR on Kyoichi. To make the matters worse they never even really get back in together and never kiss so the only kiss you will see will be Chiharu kissing that random guy. Kind of frustrating.

Onani Master Kurosowa

Spoiler for a:

Basically the guy likes a girl and she seems to like him back but then it turns out she likes his best friend and they start dating while main guy watches how they kiss and rages silently.

Break Blade

Spoiler for a:

Only NTR in fact and not in act. What I mean there is a love traingle the main guy coming back to aid his best friend who is the king of the country being invaded. It turns out that the king is married to the main guys love interest who was also his childhood freind. As the story progresses in the manga, it would turn out that the queen still has feeling for the guy and there are some moments that may be interpreted as romantic moments.

Nana

Spoiler for a:

Pretty much stuffed with adultery and cheating, couples breaking cheating on each other then coming together then breaking apart and cheating some more. Never could understand why poeple liked this soap opera. Can see plenty of stuff like that in mexican soap operas.

Macross

Spoiler for a:

In macross series the main guy likes the main girl and it seems going fine but then it starts falling apart, she becomes and idol and he is a pilot, she becomes engaged to her cousin and the main guy has to watch her and her cousin kiss a lot on films and so on. Luckily for him he finds a better girl (bit older than him and a bit tsundere) so all ends well for the guy while the main girl has her life broken, tries to return to the main guy but he denies her, so its a sort of Netorare justice series so if you are angry by the netorare you can watch this series where nTR'ing girl gets a bad end she deserves.

Kimikiss Pure Rouge

Spoiler for a:

Has a bit that makes you feel NTR'ed if you support the main couple. It is not that bad and at first neither of them feels like they are betraying or being betrayed.

Good ending

Spoiler for a:

An obvious NTR title. Mostly because of Shou. Shou is the girl the main guy likes and they are almsot to go on a date and even arrange the date time but on that very day Shou meets her sempai on whom she has a crush on and calls the main guy and lies that she cannot come to the date while at the same time dating her sempai.

Her sempai is a player though and she eventually breaks up and the main guy being a mr good guy helps her to get over it and she falls for him but he is in love with another girl, but that abnother girl also pull a slight NTR on him when she agrees to go on date with the other guy while never before going on dates...So its kind of a double NTR though Yuki's ntr is very slight. I think this ntr business and also the fact that Yuki is probably not virgin (we see few flashes where it shows seemingly Yuki having sex) which is big for main shounen romance girl is what made the otakus rage so much that the author even had to close her blog (though the author was quite a drama queen herself I have to say).

Kimi no Iru Machi

Spoiler for a:

Eba dumps the mian guy and starts dating her friend. Though the story is bit complex there and Seop worked his ass to show that nothing between the friend and Eba happened in terms of physical relationship to calm down the fans. It still has a slight NTR feeling though.

REC

Spoiler for a:

The main heroine ends up almost having sex with another dude because feeling in debt for him . She was all naked lying in bed with him on top of her but he did not penetrate her as he felt guilty in the end but the main heroine was ready to go all the way for a silly reason. To make it worse she was going out with the main guy and never told the main guy about her little adventure and kept on living with those sugary happy smiles as if nothing happened. Thats where I think the author lost most his fans.

Yume de Aetara had similar situation where heroine Nagisa almost end up being married to some dude just because she pitied his child who wanted a mother, while leaving the main guy and their relationship in the dust. It all ended up well because the guy had a kind heart and when he realized that she was forcing herself just to make his boy happy he let her go (the damned boy still whined and was against it, oh how much I wanted to kill that annoying little shit, the little bastard even kissed her (on the lips) in the end before the main guy could).

Yuutai Nova

Spoiler for a:

The main guy gains the ability to leave his body and comes to the spiritual visit of his crush just to see her having drunk sex with some guy and then get involved in the gangbang (no its not a h manga). Luckily the main guy is consoled by the other girl who can leave her body as well but in the end it seems like that other girl could also pull an NTR on him, however before its cleared the manga went on hiatus.

Kannagi

Spoiler for a:

It was blamed for having NTR but this one was ridiculous - the girl was revealed to have had an ex-boyfriend and chose his side by the very last chapter it released before going on hiatus - it went to hiatus for two reasons mangaka's health issues and extreme bashing it received (burning manga volumes and placing videos on youtube for example). Well it was a sunny moe series at that point so in a way otakus didn't expect such theme to be dropped in but it was still ridiculous.

Chigusa x Pon

Spoiler for a:

Well this non-h manga is bit on a retarded side - a boy and a girtl become a couple, then the girl gets drugged by the other guy then stripped and have made sex and the photos of that are placed on the Internet and the hero sees it. Again it is a not H manga though plot seems to suggest it to be one, and then the couple hit the hard road of overcoming those issues. What is unrealistic in it is that the main guy and the guy who raped his girlfriend become buddies - though shoujo's are infamous for having competing bishies become pals or at least friendly rivalries even when they are over jealous, that part was really pushing it.

Usotsuki Paradox

Spoiler for a:

This one is a bit different - the girl has a boyfriend far away and the main guy starts getting closer to her (physically) even though knowing that it is no good. The girl is annoying though as she doesn't try to push him away and enjoys his advances even though being in a supposed happy relationship.

Suzuka

Spoiler for a:

Only a very slight NTR feeling in there.

Ginen Shounen

Spoiler for a:

Another obvious title. Follows pretty much every possible NTR trope. Though in act itself it still doesn't happen but it plays with NTR strings a lot. It also seems like its more of a Type B the longer the story goes.

Full Metal Panic

Spoiler for a:

Chidori has her first kiss stolen by Leonard and then gets kissed few other time by him. Her alter persona doenst seem to mind being with Leo as well while the main guy suffers in the meanwhile. Not really heavy but it has NTR feeling.

Rave

Spoiler for a:

Only the very slight as the main girl gets her first kiss stolen by the main evil guy in front of the main lead.

Momoiro Peanuts

Spoiler for a:

As you mentioned.

Mysterious Girlfriend X

Spoiler for a:

Play a few NTR strings, where it leaves you guessing did the main girl 'cheated' or not.
