"I can't take it anymore! I'm leaving!"

"Treating me, a helpless and incompetent person, like a convenient tool! I'm not Onii-chan's possession!
Even though you're overprotective, you never give me any pocket money!
If you're going to treat me like a nuisance, die from overwork! How do you even have the will to live!
You say 'Don't act spoiled,' but you're the one who's spoiled!
You're always messing around with your own convenience. Are you trying to make a mess out of my life?
Are you trying to make me eat your food?
I'm going to break free from Onii-chan and walk my own path. That's right, Onii-chan.
Onii-chan."

"I run away from home with great vigor and begin a new life in the seaside house my grandfather left behind."

"From now on, I'll do everything by my own power, on my own responsibility.
I'll take back the youth I lost! I'm throwing away everything I've built up until now... but..."

"Wait, why are you following me, Onii-chan!?"

"What about work? What about school? What are you going to do about the house you left behind?
Onii-chan, who comes to wake me up even though it's night...
Onii-chan, did you properly report it?"

"You're not independent at all! Isn't this just Onii-chan's sexual possession (toy)!"
