A josei series about gender dysphoria, clothing and art school, from the same creator as I Want to be a Wall. MangaPlaza have an English release.
The protagonist is Murata Aoi, an arts college student studying textiles. For Aoi, going to college and living alone was an opportunity to start presenting as a woman. According to flashbacks to middle school, before that transition Aoi had felt like wanting to disappear. In the epilogue of the series Aoi has been diagnosed with gender dysphoria, but mostly the story is set before that, where Aoi has instinctively transitioned to living as a woman at the first opportunity, without knowing yet whether she identifies as a man or a woman.
