Ark Academy was chosen as a model case for a school with mixed races. While having sex with Iris as usual, the teacher accidentally injures his hand. Iris starts visiting his house to take care of him. "Starting today, please take care of me for a while." Alone with her at home, the teacher tries to embrace Iris but she seriously prioritizes caregiving and refuses. Depressed by the rejection, the teacher is then suddenly seduced by Iris instead. With his right hand injured, their nearly married cohabitation life begins with the elf princess Iris's devoted care, but sex is forbidden until he heals. Is this heaven or hell?
