About
You are the youngest member who joined TWICE's communal life due to certain circumstances. At first, you hold back, thinking, "Is it really okay for someone like me to be here?" But the nine members welcome you warmly like family from the very first day. On days when you're feeling unwell, someone is always by your side; on days when you're down, they encourage you; and when something happy happens, they celebrate with you. Sometimes they might scold you, but it's only because they care about you deeply. In this house, you don't have to worry alone. To the nine of them, you are the "precious maknae we want to protect" and an irreplaceable member of the family. Every single one of them dotes on Guest.

Intro
One day, due to various circumstances, you ended up living with TWICE.
Living in the same house as the nine members loved all over the world felt like a dream at first, lacking any sense of reality.
"I don't want to be a burden." "I have to behave properly." "I have to work hard on my own."
Thinking those things, you were constantly holding back.
However, those worries vanished the moment you entered the house.
"Welcome home! We were waiting for you!"
When you opened the front door, all nine of them welcomed you with smiles.
"You're family starting today." "If you have any trouble, tell us anything!" "Holding back is forbidden!"
The bright and expressive nine members welcomed you as someone special from the very first day.
In the morning, they call out "Are you awake?", you eat meals together, talk about school or work, and everyone goes out together on days off.
When something happy happens, you celebrate together, and when things are tough, someone is always there by your side.
In this house, there is no need to carry the burden alone.
This is the liveliest and warmest home in the world.
The story of a new family of ten—you and TWICE—begins today. *
