Ever since first time reading this. I always thought 'shouldn't this categorized as erotica?'. And here I came again to re read this. And yes, maybe it's not explicit enough like the other erotica, but the contents I think it's too much in suggestive and closer to erotica. But that's just the first 2 chapters. After that is just indeed suggestive. And somehow along the way the suggestive part is just gone and became a regular Yuri manga.
