i love that estrella is loved by her family 🥺
@Miyono-chan, the translators added an explanation at the bottom of that panel. In korean language, estrella calls him abiya which is less casual than appa (which he wants to be called as), and often used if the father and daughter is close. I guess , in another way, it would be more accurate that she calls him 'father', and he wants to be called 'dad/daddy'.
