Kocchi Muite Glare
Nishina Zen is an ordinary man who wandered into another world one day where everyone has animal ears. He got into an altercation and was saved by Alivian, a member of a government bureau who takes him in and explains this world. But while they're talking, Zen reacts to one of Al's words as if it were a "command," leading to the realization that Zen is a sub. He demands that Al (dom) take care of him, and they end up living together, much to Al's surprise, as his glare is usually too much for even neutrals, but Zen doesn't seem to mind at all. In fact, "playing" with Zen seems to help manage his glare so others are effected less as well. It all seems too good to be true, and Al feels guilty for using Zen, while Zen is starting to feel romantic feelings for Al that Al seems unprepared to accept. No trigger warnings.
Chuuken Bodyguard ga Nisemono Reijou no Uso to Karada wo Abaku made.
Reiko Takanashi was isekaied into the body of the villainess, so she's been trying her best to be a good person and win everyone over ever since, especially her bodyguard, Takaomi Ichijou, who killed her in the original story. But when Takaomi meets with the heroine anyway, Reiko begins to think maybe the only way to avoid this is to fire him, causing him to go off the deep end and assault her. But that's just how deep his feelings go, right? Could have been a good story without the assault. Trigger warnings: drug(roofie), kidnapping, noncon.
I've Reincarnated as the Villainess, but the Stubborn Crown Prince I Was Supposed to Lose Is All Over Me!!
Isabella isekaied into a dating sim as the villainess, and despite her best efforts, the story followed the villainess exile route...wop wop. While attempting to go into hiding until her dad can figure things out, Isabella is kidnapped and sold into sex slavery, and soon her first night is purchased by a masked man looking to get some experience in before his wedding. But what Isabella doesn't realize is that the masked man is obviously her ex, the prince (Samuel) who jilted her, and for some reason, he doesn't recognize Isabella either, leading the two of them to start a relationship again, just a little too late and a lot more risque. A tired trope with nothing in particular to distinguish it, but read if that's what you're looking for. Trigger warnings: cheating (implied), sex trafficking, sex work.
Igyou Atama-san to Ningen-chan
Chika is an ordinary woman who lived a life of constant abuse by her parents until she nearly died and was transported to the world of heteromorphic heads! (Meaning heads all have different shapes.) She was found by professionals trained to take care of such displaced humans and ended up living with Raz, a man with the head of a daft punk member if their head was all black and they had a venom smile for a mouth. Even though humans are treated as "pets" in this world, the scary-looking Raz has fallen head over heels for his Chika and she loves him too, though she can't express it as trauma has left her unable to speak. With the help of Raz and his friends, Chika slowly begins to heal from her trauma and bridge the gap between her and Raz so they can truly be in love. A very bizarre setup, but it's fun world building. The story does feel a bit rushed though. Trigger warnings: abuse, attempted suicide, violence.
