I need you to give me an example of what you mean by that.
Because most of these fluffy, cute, wholesome manga, even the cute-girls-doing-cute-things type, are
actually under shounen demographic.
[like
Manemane or
Tsumiki or
Yotsuba etc.]
Fluffy under Shoujo demographic -most of the time- means fluffy romance with a female main protagonist
[like
Koiseyo or
YubiRen etc.]
