Looking for a manga where INFIDELITY (cheating in a romantic relationship) is the main theme or one of the main themes. Not just a brief mention but one of the main topics that the manga deals with, "main" enough that if you wanted to summarize the manga this is a theme you would immediately think of. I do NOT want a manga where it's just a few pages about infidelity; I want something that seriously explores this theme.

I prefer shoujo, josei and BL recommendations, but a good non-harem seinen manga is also acceptable. Prefer a serious story, not a comedy.

Doesn't have to be full-on sex outside the main relationship to count as cheating; as far as I'm concerned even kissing or having romantic feelings for someone else other than one's committed partner is cheating.

Examples:

Cappuccino - josei
The Cornered Mouse Dreams of Cheese - josei/BL hybrid
3D Material - josei
Overdose - yaoi
Kare Wa Tomodachi - shoujo
Tsugou no Ii Kimi - yaoi
Pretty Poison - josei
Waltz With a Black Cat - yaoi
Nana - josei
Thirsty For Love - yaoi
Happiness Monopoly - shoujo
Tramps Like Us - josei
Prince Charming - yaoi
Girlfriend - seinen
Love in the Afternoon - yaoi, 4th one-shot
The Limits that Desire Allows Us - yaoi but lots of straight content
A Place For Half a Rent - yaoi, last one-shot

More like these please.

Mel Kano it happen later in the manga.

Thanks for the rec! Re: Mel Kano, is infidelity a major theme? Because if it only occurs briefly rather than regularly then it probably does not count - plz confirm. Still, thanks for the suggestion either way!

BL
Complex
Scarlet
Yume no Kodomo
Not/Love

Josei
Bara to Saiaku no Tamashii

School days maybe?

Thank you to everyone, RIP131 & rabbitpower (yay BL!).

@rabbitpower, that josei Miyamoto Kano manga you recommended, Rose and the Worst Soul, looks SO DAMN AWESOME! I can't believe it's not scanlated... ;_; Hopefully someone will pick it up soon.

My all time favorite: Haru yo, Koi has some explicit xxx and yuri

Love Blog!! - josei
Koibana! - Koiseyo Hanabi - shoujo
Strobe Edge - sort of...but not really

Thank you skat (YAY YURI!!!) & chullan1819 (haven't read Love Blog but will now do it).

Pumpkin and Mayonnaise - josei

It's by Takaguchi Satosumi! I am dying to know how the story ends. I only have volume 1-3. So much UST and cheating going on in the story, the drama is crazy. There is even a male character with transgendered issues in it.

Wife cheated on her husband:
Gerard to Jacques: Natalie - Gerard
Bronze no tenshi: Natalia - Puskin

Natalie vs Natalia What a coincidence! Try those 2 mangas out and compare the 2 women, who is better at cheating then
