- Loveless: Ooh boy, where do we start? Soubi and Ritsuka, Soubi and Kio, Soubi and Seimei, Soubi and Ritsu-sensei (one-sided, admittedly).
- And then let's not forget the male Zeroes who, despite being kids, act like an old married couple.
- Nisei towards Seimei. In a biiiig way.
- Yayoi has a brief moment of this upon meeting Ritsuka for the first time:
Yayoi: Aoyagi Ritsuka. He's pretty. Like a girl.
- Also, in regards to the Les Yay Koya and Yamato, adversaries in the third and fourth volumes of the manga. Note that this was actually made more explicit in the anime, which in their first scene showed them kiss on the train when the manga just had them hold hands, as if it was just to make sure we weren't mistaken as to what was going on.
- Seimei is one hell of a Yandere towards his brother Ritsuka.
- Both Natsuo and Youji have taken a shine to Ritsuka, especially in volumes 10 and 11. Leaving Nagisa on their own to keep an eye on him, enrolling at his school, invading his space by draping themselves over him, teasing him by asking where his name is... There were hints of it way back when he fell asleep in the same bed with them.
