Hitsuji no Kawa wo Kita Kemono
Daichi Kusakabe is a college student who is stunned to meet his annoying sister's new knockout boyfriend, Jun Igawa, who seems to be the perfect man. Although Daichi has his guard up with Jun at first, they end up fast friends, hanging out at least once a week as they bond over shared childhood trauma. But after Daichi wakes up in Jun's bed with no memory of how they got there, things start to unravel, and it turns out Jun is not at all who Daichi thought he is. But for some reason, Daichi can't let Jun, or his true name, Keigo Tatsumi, go. An interesting story about an unhealthy relationship that somehow turns things around by the end. Trigger warnings: lying/manipulation, drugging, noncon, attempted rape.
Monster Master
Kaname is a young delinquent who suddenly lost his father without getting to say goodbye. To his surprise, the handsome company president, Sena, shows up at his dad's funeral and says he'll become Kaname's guardian due to his friendship with Kaname's dad. But very quickly Kaname realizes he doesn't want a fatherly relationship with Sena, and it seems Sena might not want that either. The timing is so fast it just comes off as wacky and the couple didn't stand out to me. Trigger warning: incest themes(guardian), statutory rape(?).
