Goodbye My Beloved, Leaving Me in Desolation

On my 20th birthday, I accidentally fell down the stairs. I didn't get a concussion, but I unexpectedly got a system.

As long as I spent money on people who loved me, I would get double the amount back.

So without hesitation, I took my best friend to buy a mobile phone.

While she held the phone with satisfaction, I suffered a double loss.
