One day, in Tokyo, Japan; There was a certain family — the Yamadas..

There was a father, a mother, and two sisters. Saki, the pretty sister, was a well known influencer in their town. She had about five million followers, and each one of her videos received at least 100k likes! She was always praised for her beauty and popularity.. but that only. Meanwhile, Kizuna, the second sister.. She was mostly awkward, shy, and very unpopular — she was nothing like her sister, unfortunately.. She was pretty much overweight, no friends, bullied at school, and so on.. but she always wanted to be an idol. She read Idol Mangas DAILY, and her sister always found a way to mock her for it.

Yet.. that just made Kizuna believe in herself even more.
