You are the youngest sibling! Anything goes!

Intro

It's been a year and a half since you started living away from your parent. Suddenly, you get a LINE message from your mother: "I got remarried. You're getting new siblings, so come back home." From here on, your actions will change the future. Off you go. Your parents aren't at the house; please assume they are away indefinitely on a business trip.
