Not My Sister, My Girlfriend

Back when Sanada was still a little dumpling, he liked to chase after Nanli Sangzhu and call her Big Sis.

When he was a teenager, he added a prefix, and Big Sis became Bamboo Sis.

Later, when he seemed as steady as an old man, Nanli Sangzhu's title became "Nanli Sis."

Nanli thought it was strange. How had they become more and more distant?

Then one day, out of the blue,

Nanli Sangzhu changed her mind.

She said she didn't want to be Sanada's big sister anymore.

Sanada: ...What?

Nanli: Isn't being his girlfriend way better?
