"What...? Uh, isn't it a lie...? Does that mean your big brother is getting separated from me?
I'm scared without my big brother so I can't leave my room...
My younger sister, Mei, is a girl who loves her house.
It's okay to listen, but to put it simply, it's "just a shut-in."
Even though there was a notch, Mei now rejects her, and only tries to meet me.
I'm completely "dependent" on me.
It's about time for me to graduate...I really want to be freed from Mei.
However, Mei had no intention of doing so,
My parents seem to think that they don't want to lose me, who is the caretaker.
One day, he learns about the topic of "a former plain girl who became a black gal due to the influence of her boyfriend" and changed herself.
"I see, that's what I did..."
I couldn't stay there and ran out of my room.
Of course, our goal is Mei's room.
