The supporting character's harem is very normal - Chapter 461 Karol Magic Academy.

There was a big scandal in the Mu family.

The real daughter of the Mu family was switched by the nanny since she was a child. The Mu family didn’t bring her back from countryside until 17 years later!

After the true daughter returned – There was no affection, only sympathy.

The Mu family parents asked her, “We have a deep relationship with Yaoyao. We can’t let her lose face. We can only announce you as an adopted daughter to the outside world. You won’t blame us, right?”

Her fiancée also said: “My fiancée can only be Yaoyao! Get out of here country bumpkin.”

The attitude of her older brother Mu Qingyi was even more complicated.

Yet despite all that, the real daughter, Xu Xinduo, said indifferently, “It doesn’t matter.”

***

From a young age Xu Xinduo could swap bodies with a certain teenager. That teenager would always exclaim in an annoyed tone, “Let’s switch bodies, I just don’t feel like taking piano lessons.

Xu Xinduo helped the teenager to win various trophies, become a top student and honed his noble temperament and talent after taking over his body.

***

At a banquet, everyone in the Mu family watched as a rich young master strode towards Xu Xinduo and said, “Be my girlfriend, although you are from a small family… you are very beautiful.”

With a smile Xu Xinduo replied, “I’m starting to miss my parents already.”

Such a quick change of attitude?!

Note: Here “switching bodies” means swapping of souls. It’s temporary and doesn’t involve any physical changes.

The hearse with the weird odor slowed to a stop before the entrance. The sound of pebbles could be heard bouncing on the ceiling. There were footsteps coming from the corridor, and there seemed to be someone sawing next door. The door knob to the room rattled slightly, and the faucet in the bathroom kept dripping even though it had been screwed shut. There was a rubber ball that rolled on its own underneath the bed. Wet footsteps started to surface one after another on the floor.
At 3 am, Chen Ge held a cleaver in his hand as he hid beside the room heater. The call he was trying to make was finally answered. “Landlord, is this what you meant by ‘the house can be a little crowded at night’‽”
