The Betrayal Knows My Name/Ho Yay



 has mostly males in the cast very occupied in confessing their mutual admiration for each other and even have a pet dragon called "Sodom". Several sites tag this series as shounen ai but it officially is shoujo. To be honest, its pretty clear why people would make that assumption.

Other

 * Fuyutoki/Takashiro: Fuyutoki cares very deeply for Takashiro, probably more than a butler should for his master and gives an almost Love Confession in episode 20.
 * Plus everyone's adoration of Yuki, including the main villian aka Reiga.
 * In episode 1/chapter 1 a bully grabs Yuki, gets close to his face, and says he has a pretty/cute face.
 * Hotsuma's Tsundere behavior around Yuki, making it clear that he does care about him despite his Jerkass behavior. And how Yuki worries about Hotsuma and says that he likes him in chapter 11.
 * Uzuki and Yuki. Yuki is quite determined to be Uzuki's friend despite Uzuki claiming he dislikes him though he does eventually come around.
 * Takashiro/Yuki. Take for example their conversation about sleeping together in the same bed in chapter 7. Also, during episode 13 when Yuki's best friend Kanata reveals himself as Big Bad Reiga, he tries to kill him with ice spears but he notices Reiga's stabbed Takashiro with the ice slabs because Takashiro shielded Yuki.
 * Chapter 10: Tsukumo saying that he likes Yuki and he also likes Shuusei.
 * Chapter 21: Yuki saying that Kuroto is very pretty and Senshirou agreeing. Also, there's a chart that depicts Tsukumo and Touko with a heart pointing to the both of them, same thing with Hotsuma and Shuusei. It says "true love".
 * Don't forget about how Dr Isuzu is always looking for an opportunity to examinate Luka's body. The latter is understandably annoyed.
 * If Luka's comment (in the manga) about being a male is actually true, then  obsession with him certainly counts.
