Translated from here.
Foods are used to greatly increase resonance level (how much they love you, I guess) and improve each character’s condition. Here are each character’s favorite foods. Foods they love will be in bold.
Food names will be in English XD Feel free to correct me if I made any mistakes in translation, my Japanese is still weak and English ain’t my first language.
