Egao no Taenai Shokuba desu.

The Arts are made up of three types: Performing Arts (Music, Dance, Theater, Cosplaying, Acting, etc.), Visual Arts (Painting, Drawing, Film Making, Animation, Video Game Creation, Photography, etc.) and Literary Arts (Novel/Light Novel Writing, Manga/Doujin Writing, Lyric Writing, Journalism, Magazines, Editing, Dictionary Writing, Ghost Writing, etc.). While Performing Arts and Visual Arts have tags on MyAnimeList, Literary Arts do not, so this interest stack is rectifying that. Literary Arts have a long history with anime like the other two art forms, so this includes a wide variety of them. It may also include some that are about being passionate for literature rather than writing itself. Some series are excluded if they lean more towards Performing Arts or Visual Arts than Literary Arts, such as Kodocha, Saekano or The Pet Girl of Sakurasou. While some series may have major characters who are novelists, it needs to have Literary Arts be an important aspect of the plot in order for it to be included. Also, there will only be one series per franchise for the sake of variety.

Explicitly Cannon Couples and Hard Subtext Shows. Subtext shows listed here have substantial content and not just a little bit of teasing here and there. Subtext can also be an unspoken focal point of the series. These are shows I can actually recommend and like enough to suggest checking out.

-some popular shows in here simply worth mentioning because it would be criminal not to mention them.
