Yuma and Hotaru have been best friends since childhood. Yuma would protect Hotaru from things such as bullies, and made it her job to look after her.^[2] Now, the two are second-year high school students, but Hotaru is anything but innocent. Yuma gets her first boyfriend and is nervous about it, so a more experienced Hotaru suggests a "dress rehearsal" to help her out.^[2] The helping out later on leads to a deep kiss with Hotaru, who says that Yuma now knows how to kiss a guy. This leaves her thinking about how much better this kiss was than the one she had shared with her boyfriend.^[3] As time goes on, Yuma worries that her boyfriend will find out what is going on between her and Hotaru.

Yuma is in her second year of high school along with her best friend Hotaru. When she finds her first boyfriend (Takeda) she is not sure how to react so she asks Hotaru for advice. Yuma is surprised though when it appears as if her friend is flirting with her. She cannot explain the good feeling she gets when she French kisses Hotaru or when she gets fondled, and worries that Takeda will catch her in the act. In the second volume he decides that the two should take some space apart, and Yuma comes to terms that she is in fact cheating with Hotaru. Her feelings still remain conflicted though as she does not want to hurt him so she remains as a friend. Yuma finally confesses to Hotaru in the fifth manga volume that she has feelings towards her but is rejected. She then turns to Takeda after feeling like she had been used the entire time by her.

Hotaru is Yuma's best friend since they were children. It is shown that early on Yuma would always protect her from things such as bullies at school, but over time she surpassed her in being bold. She eventually went out with many different boyfriends, but from Yuma's point of view she would never pay attention to any of them. She is shown to be aggressive with her feelings towards Yuma, making the first moves on more than one occasion. Yuma senses though that there might be trouble between her and Fujiwara despite Hotaru's strong attitude.

Takeda is a classmate and friend of Hotaru, and is Yuma's first boyfriend. In the story he comes across as a friendly understanding guy who is aware of his girlfriend's shyness, and does his best to remedy the situation. He is unaware of Hotaru's advances towards Yuma, but later senses that she doesn't hold enough affection for him. Takeda eventually ends their dating relationship and tells Yuma to find out what she wants for herself before they go any further. The two remain friends until he starts to worry that Yuma may be in trouble with another person at Fujiwara's suggestion. He asks Yuma (who is crying) out again at the end of the fifth manga volume not knowing that she was just rejected by Hotaru.

Fujiwara (藤原)

Voiced by: Daisuke Ono

Fujiwara is Hotaru's boyfriend, and is friends with Takeda. Early on in the story he suspects that his girlfriend may not be committed to him but initially doesn't say anything. This changes later on though when he confirms his suspicion, and drops a hint to Yuma that he knows. It is suggested that he is physically abusive to Hotaru which causes concern for Yuma when she sees that Hotaru has a black eye. Fujiwara has stated that he plans to use the knowledge of the secret relationship between the two girls to his advantage in the form of sexual favors. The two dismiss his idea as a practical joke not knowing that he has "evidence" that implies the opposite. He later lies to Yuma saying that Hotaru is moving to get away from her, and Takeda about Yuma being in an abusive new relationship.

The English version of NTR: Netsuzou Trap has received mixed reviews from manga critics. Rebecca Silverman from Anime News Network gave the series an overall C+ grade. She felt that it is a "fairly unusual yuri story", similar to what is seen in yaoi, because of the sexually aggressive nature of the romance. Silverman stated there is a strong indication that Hotaru is using boys to get over Yuma, and that Hotaru not appearing to particularly love Yuma might be masked feelings due to past problems. Although Silverman felt that it is good that the series offers variety for those who like this kind of story, and that, unlike with Hotaru, readers get a better feel for Yuma's character, she felt that the story's "less consensual romance" is uncomfortable, and critiqued the artwork of the character's upper bodies; she did, however, praise the artwork involving the character's legs.^[24] Journalist Kat Callahan agreed with Silverman on the series not being a typical example of a yuri series. She writes in her review that the series deals with the cycle of abuse when it comes to Hotaru, and that Yuma is also a victim as a result.^[25]

Yuricon founder Erica Friedman described the story as "creeptastic", saying that it is about girls who get naked to do stuff with each other while their boyfriends are "conveniently not in the room with them".^[26] Sean Gaffney from Manga Bookshelf wrote that the first volume is not for its intended audience and recommends it instead for adult men who think that girl-on-girl action is attractive.^[13]
