Two different manga share a very similar title, but the most direct match for Sweet Heat is a yuri comedy set in the world of women's professional wrestling. The story centers on two rival wrestlers who are secretly lovers living together. The hugely popular babyface known as Butterfly Cat, whose real name is Haruzora, and the ruthless heel called The Wicked Witch of the West, named Eiko, wage no-holds-barred battles inside the ring that drive audiences into a frenzy. Their public personas could not be more different, one being a beloved hero and the other a冷酷无情 villain, yet they share an apartment and a romantic relationship hidden from the world. At home, their sparks fly in a completely different way, creating a comedy driven by the gap between their fierce combat lives and their private affection. This ongoing series, published by Shogakukan and written by Koharu Biyori, is a unique blend of sports action and romantic comedy where both professional wrestling and love are fascinating precisely because they are so complicated.

A different and unrelated manga exists under the longer title Sweet Heat Before Falling in Love: The CEO and His Fated Omega. This series, created by Yun and published in English by Seven Seas Entertainment under its Steamship imprint, belongs to the omegaverse genre. The plot follows Uiko, an omega office worker who hides her true secondary gender by posing as a beta to avoid relentless advances from alpha suitors. When she unexpectedly goes into heat and can no longer suppress her pheromones, she seeks refuge at AΩ, an exclusive salon where omegas can safely ride out their cycles by pairing with a compatible alpha. There, she is matched with a mysterious, masked alpha whose identity she does not know, and she experiences an overwhelming and unforgettable encounter. Returning to work, Uiko begins to suspect that her irresistible mystery man might actually be much closer than she ever realized, possibly her own CEO, Takamura. As their relationship develops into a real couple, later volumes deal with the intense passion and possessive urges that arise, such as when Uiko returns from a business trip with a male coworker, triggering Takamura’s protective and dominant instincts.
