The main character is a good-looking husband who loves his wife.The story is about him “being cheated on.”
“Melancholy of the Betrayed”is different from other cheating manga in that the focus is on “the cheatee.”
The main character loves his wife and is a good-looking, higher earner; a husband anyone would be envious of. His wife Aiko finds him too nice and lacking in excitement, so she begins an affair with her boss at work.
It was meant to be casual in the beginning, but she becomes increasingly serious and plans to make her boss her own by breaking up his family and pinning all the blame on her husband.
In one sense, you’ll find yourself unable to take your eyes away from the ending which takes a bracing look at the true feelings of Aiko, the worst cheating wife in history, who is never discouraged and always misinterprets things in her favor...

主人公是深爱妻子的帅气丈夫
描写拥有这样丈夫的『被出轨的一方』的物语
「被背叛的田川的憂鬱」和一般描写出轨剧情的漫画不一样、是以描写「被出轨的一方」为焦点的作品。
主人公是既深爱妻子还长得帅气，收入又高是谁都羡慕的好丈夫。可是太温柔缺少激情的原因妻子蓝子和上司在上班公司内部快乐的享受出轨生活。
刚开始只是玩火而已，没想到越来越认真用情起来，所有的借口都是丈夫的原因，一直在策划拆散对方的家庭最后和上司在一起生活。
还有另一种意思就是，坚持下去可以有结果的错觉。
也算是史上最凶的出轨妻子蓝子、
不知何时、可以回归女人纯真的内心，等待这个结果让人不能不追此剧。。。
