On my first meeting with my fiancée, a young duchess of the same age, she suddenly screamed and fainted upon seeing me! What the... Why...!? Did you remember something? Are you the villainess? Am I the one who causes your downfall due to my infidelity? Well, even if you tell me this while crying, I can't really do anything about it at the age of ten... What a harsh setting for me. But, there are many things we can do to prevent such a thing from happening. Let's think about it together! Come on, trust me.
