Senior Sister, I'm Really Just Pretending with Them

There's a frosty senior sister who keeps an eye on you.

She'll watch to see if you're studying hard, if you're slacking off, and if you're giggling and joking around with girls from other families.

If your senior sister catches you in the act, then congratulations: you'll get a sound thrashing from the third-rank Heaven-tier Frost Sword Immortal!

But she'll wear a chilling smile after doing something foolish...

But she'll feed me medicine and porridge when I'm sick...

But she'll shed tears when I put myself in danger...

This book is also known as My Beautiful Iceberg Immortal Senior Sister, Immortal Sister, the Empress and I Are Completely Innocent, Junior Sister, Hear Me Out, the Young Lady and I Were Only Pretending, and Auntie... What Are You Smiling at?!

P.S. Long time no see. I've missed you terribly.
