Disclaimer: Even though the uke has a girlfriend, he totally admits he is gay. The seme is bisexual since he has a serious relationship with both sexes.
Disclaimer: This is for the second introduced couple. I am not sure if the uke is gay, but I think this is his first and only sexual and romantic experience. The seme is bisexual.
Disclaimer: In this story, the demons are fine with both sexes. So, the seme is bisexual.
Sequel: Kimi to Kore Kara
Prequel: Konya mo Nemurenai
Disclaimer: The seme is fine with both sexes whomever he loves. Then, the uke has romantic and sexual feeling with the seme's employee.
Disclaimer: The pairing here is confusing though. I am not sure if I put it on the list.
Disclaimer: For seme, it looks like he is straight. However, he mentions he is fine with anyone as long as there is a hole, and the face must be his type. For uke, he looks like demisexual. But, there is a scene that shows his aesthetic attraction towards another character aside from seme. So, yeah.
Disclaimer: The seme seems like bisexual for me. In uke's case, he gets married, but all of his sexual experiences are towards guys. He never touched his wife.
