Reincarnated as Parasitic Tentacle - Chapter 48: Rebecca (18+)

It was said that the young lady from the Chi family, who was raised in the countryside and didn't even finish her sophomore year of high school, was brought back home. People were looking forward to seeing her become a laughingstock.

Unexpectedly—

Why did the grandchildren and sons of Kyoto's top prestigious families eagerly join the same class as Chi Gui?

Why did a world-renowned medical expert converse so kindly and familiarly with Chi Gui?

And then there's the ruthless, unapproachable prince of the Fu family, whose demeanor did a complete 180, showing off Chi Gui daily in chat groups?

Others:

“My girlfriend cooks well!”

“My darling plays the piano well!”

Fu Si: “My wife excels at dissecting corpses.”

Crowd: …

Chi Gui: …

These people are so annoying.
