Looks like he catches his crush having sex with a teacher. Then he has sex with her on and off while she is still doing the teacher. His coworker likes him and eventually he has sex with her and she turns out to be a virgin. After a while of having sex with his coworker the black haired chick is vulnerable because the teacher probably was done with her so they have sex again. His coworker finds out and breaks it off with him. He has sex with the black haired chick for awhile longer and then eventually realizes that hes done with her and that he doesnt love her so it seems to end with him growing up.

The protagonist (Furuda Yuuki) had a crush on the black-haired girl (Asahina Kiyomi). However, Asahina loved a Cultural Anthropology professor in their college. She explained how she was born as a illegitimate child due to an affair between her mom and an unknown man, and was ridiculed for it throughout her childhood. When she got into college, she approached said professor and talked to him about her circumstance, as his field is in Adultery. Eventually she fell in love with the professor (daddy issue) and basically repeated what her mom did by having an affair with the professor, who is a married man.

Furuda saw Asahina and the professor having sex one evening, and later he approached Asahina about it, saying he wants to understand what she is thinking. Asahina took Furuda to a hotel and they had sex; they also went on dates and did lovers stuffs. However, when Furuda confessed his feelings for Asahina and asked her to reciprocate, she refused and explained to him that the reason she did all those things was because she wanted Furuda to understand what she was feeling right now, i.e. the feeling of loving someone so badly that you cannot forget about them, even if you know your love is futile and without future. She told him that her college thesis is on "Adultery/Immorality" (不倫), and she did all those stuffs as a way to gather data for her thesis.

After that shocking statement, Furuda avoided Asahina and threw himself into his part time work, and tried to be more social with his coworkers. One of his coworker, the short-haired girl (Inoue Serina), confessed her love to Furuda and they started going out. Their love went on smoothly, and Furuda convinced himself that he loved Serina. However, when they accidentally met Asahina on campus, he got too worked up and Serina realized that Asahina was the one Furuda loved (she said he couldn't even call her first name (Serina) in front of Asahina.) He tried to deny it at first, but couldn't bring himself to lie to Serina and confessed that they (him and Asahina) had sex. Serina and Furuda broke up later.

Asahina later approached Furuda after his breakup and explained her past to him (see paragraph 1.) She said that she was glad she found Furuda, and that they are two person cut from the same cloth, since even when both of them "realized the person they love has a family/lover, they continued to follow their lust and had sex with that person" ("that person" being the professor in Asahina's case, and Asahina in Furuda's case.) Furuda and Asahina then decided to continue to engage in sex knowing that they are cheating their feelings with lust.

However, Furuda later manned up and told Asahina that he doesn't want to have sex with such disgust anymore, and confessed his love to her again, saying that he wanted to make love rather than just having sex. Asahina rejected him again, but this time he accepted her rejection and went home while holding back his tears. He decided to straighten his life and tried to learn from his affairs with Serina and Asahina. Asahina sent him one last email about how she also had confessed her love to the professor and faced her and the professor's feelings head on. Furuda remarked how he needn't worry anymore since both he and Asahina will probably be able to move forward from now on.

Time skip, Furuda is living with an unknown girl. The last page ended with Furuda filling out his marriage form. The last line basically ended with "Even if people say Marriage is the grave of love, I [Furuda] have no regret. If this is a mistake, then nice to meet you."

@ irrelevance90: Thanks for the detailed summary. Then this series isnt really NTR then at all, seeing as Furuda never did stole Asahina away from the professor seeing as she's basically just playing around with him and from start to finish, it seems that Asahina still love the professor and is still willing to be with him, I suppose even if the guy gets a divorce or not.

Based on irrel's post this isn't ntr, just a lot of cheating. Can someone downvote ntr and up vote cheating?

卧槽，这剧情，但是，这画风

Well that's a bitch move to use him for her thesis and making him think he had a chance. Feel bad for the 2nd girl since she had nothing to do with this and got involved.
Who posted the pictures anyway? random person or someone related to the professor?

Base +5

@ MRVII It is ntr because the main character is not able to attain his love (bad girl likes teacher, main character likes bad girl, good girl likes main character)... its simply different from what your used to, which is probably (main character likes girl, girl gets raped/has sex with bad guy, girl starts to get confused about her own feelings for main character and bad guy, girl likes bad guy in the end) and again the main character does not attain his love.
