The Anemone Feels the Heat

If it's okay for it to be a we novel rather than a manga, "story about buying my classmate once a week" is incredible writing, and although it feels less like western wlw kinda media it doesn't really feel male gaze-y to me, it feels like young gay angst

Though it is also vaguely kinky, which may not be everyone's cup of tea
