Added note from the translator that I made sure to take into account:

The tiniest of translation notes: while in Japanese you would compare a red face (from blushing, or in this case, blood rushing to the head) to an apple, it's more common in English to use "as red as a tomato", so I pulled a sneaky edit and made the apple into a tomato.
