You're going to be my boyfriend.
I'm not going to marry you.
You aren't going to beat me!!!!
Would you please go out with me...?
Can we do our morning study sessions together...?
I thought you live by yourself.
Is my fate going to change?
Are you going to marry him?
The Kuroshio currents beckon to me.
Don't treat me like your kid sister.
I can't forget that just happened.
It's not that I like you, yet.
Things aren't quite working out, are they?
Walls exist to be overcome!!
We have to tell her... about our secret!
I want to talk about now.
Anything could happen right now!
Who is that person?

I want to grow up already!
It's a secret between you and me.
I'll Be There With You
What Should We Do Now?
All That Matters Is That You Two Are Happy
