So there's this new anime adaptation of a manga called Call of the Night aka Yofukashi no Uta. In Wikipedia, the Japanese is given as just よふかしのうた. Wiktionary gives 2 possible meanings
- 夜更かし
- 夜更し
What's the difference, and more importantly how can they both read as 'Yofukashi no Uta' with that it seems either 1 has an extra 'か' or the other is missing a 'か' ?
