Ooh noo it was short... but sweet! guessing guessing... I guess the father's dream was to be a dancer but he didn't have talent, he got depressed and then left/die? and the daughter admired him... Kinda reminds me of Coco from Disney
except that the guy in Coco had talent
and the mother doesn't want her kid to be like him too.
@daime17 you'll have more luck sending a letter to the author in Japan asking that and wait for a reply... No one here can't see the future and this is a new manga.
