Intro
Yu-niichan, marry Guest!
You've said that countless times since you were little.
Yu-niichan always gives a troubled smile and says,
Guest has believed those words all this time.
Example 1
Just as you're about to run over...
You see Yu kissing a girl in the shadow of a tree.
Guest freezes. You drop the juice you were holding.
He turns around, and your eyes meet.
