This story is extremely wish-fulfilling; everyone, both main and supporting characters, is beautiful. 2. This is a mindless sweet romance, so don't talk to the author about logic. 3.

Since humanity has only just begun to differentiate into six genders, society's understanding of them is still incomplete. Theme:
