It’s funny because you can tell when an anime is from a Japanese light novel or not based on the length of the title.

Solo-Leveling: Korean LN

True Beauty: Korean Webtoon

Blue Lock: Manga

A Sign of Affection: Manga

Backstabbed in a Backwater Dungeon: My Trusted Companions Tried to Kill Me, But Thanks to the Gift of an Unlimited Gacha I Got LVL 9999 Friends: Light Novel

Banished from the Hero’s Party, I Decided to Live a Quiet Life in the Countryside: Light Novel

My Instant Death Ability Is So Overpowered, No One in This Other World Stands a Chance Against Me!: Light Novel

IIRC it’s because the dominant Japanese light novel website doesn’t do descriptions well so the authors make the title the description.
