Have already played this as well as Nurse Love Addiction and Nurse Love Syndrome and highly recommend them despite the lack of sexual content.
Nurse Love Addiction: A cute yuri story until something violent happens and we're knee deep in a mystery story. Very clever how playing the different routes uncovers more layers of the mystery.
Nurse Love Syndrome: Totally different story, I was really impressed how realistically it described the job of a nurse. A few really good routes, plus a couple of smaller mysteries thrown in.
Yumeutsutsu Re:Master: Set in a VN game studio, so you learn a bit about the process, especially creativitiy vs. deadlines. The routes are all really different and usually really good. I was not looking forward to the Nana route, she's a fun side character but I feared she'd be an annoying love interest - but that route is a complete surprise and pretty dark. There's also a main mystery which is a bit painful to follow: Our protagonist Ai is hated by her younger sister and has no idea why. We only discover the reason on the final route and it's rather weird and admittedly pretty disappointing, but it's a very creative route nonetheless.
