The period of this research project is very long. There's a chance that you might not get to go home for the rest of your life. "Three days ago, Cristiano had specifically prepared that huge and grand proposal for you, didn't he? Isn't he the most influential Don of all of Norelia? Are you sure you want to give up on your identity as the Gallo family's Donna and go to another country with me instead?" I nod without hesitation. "Yes, I absolutely want this for myself."

Hence, I accept Taddeo's academic offer and leave Istravia without any hesitation. This time, I choose to abandon my biased family as well as Cristiano, the man I've previously loved for a lifetime.
