Shishi ni Hire
High school teacher Haruchika lives with his former student Kiyomasa, who had a troubled upbringing that led Haruchika to offer his home if Kiyomasa was ever in need. Kiyomasa turned up years later, and they've been living together ever since. But when Haruchika's current troubled student, Asako, gets help from Kiyomasa and starts following him around, it interrupts their happy life and makes Haruchika wonder what he's really bringing to the table in this relationship. I liked that Asako was an interesting side character not just used for jealousy. No trigger warnings.
Akumariage
Kairi is an ordinary school boy until one day he comes home to find a demon in his room who announces that Kairi belongs to him due to a contract made in a previous life and pounces on him. Now Kairi has a jealous, high-maintenance (male) demon as his wife, and while it's not all bad, he can't help but worry that Raj is in love with his past life, not him. This one has interesting characters and a good setup but it fumbles a bit at the last moment to rush into a happy ending without really resolving the interesting conflicts that it had built up. Still a solid read with a sexy demon though. Trigger warning: statutory rape (probably).
