He suddenly turned around, and then his clear and bright voice came from above her head.
"If I address you as 'sister' from here on, will you accept it?"
She was first stunned and then confused before eventually raising her gaze to see him looking back with immense tenderness in his eyes. His voice was incomparably soft when he spoke. "Shishi, do you know why I like being with you?"
"Uh…"
"It's because you've always given me a very warm and cosy feeling. I don't have a home and have no more family, but you always give me such a kind feeling, so I somehow can find a bit of warmth in this cold and heartless world." He paused before continuing. "From the start, I've had this childish wish of becoming your kin in our next lives, but let's not wait for our next lives, alright? Are you willing to accept me as your brother if I'm to call you as my sister?"
"Why not?" There was not a moment of hesitation in the woman's reply.
