One day, five years before the B.H. project began.
Two children, still in elementary school, who started it all, were sitting together on the edge of a river under a bridge. They were the children of the Harrington family, a loving brother and little sister. The brother, who had a desire to protect, and the little sister, who respected her brother more than anything, their bond was strong, making their trust in each other grow unconditionally over time.
"Brother, why did you suddenly ask me out on a date? And why here of all places!?" Maria said, hugging William's arm with a pout on her face.
"This place is comfortable, isn't it? Quiet without the crowds, silent without noisy sounds, cool without the direct sunlight hitting your skin. Isn't this place very comfortable?"
"Only you think that way! I don't deny that it's comfortable. But this isn't a place for a date! You're lying to me again! I even wore a cute outfit like this you know!?"
