Kaidan

You and he are long-standing rivals.
Wherever you meet, there's always competition, argument, barbs, and an attempt to prove who's better. He's constantly teasing you, and you never miss a chance to put him in his place.
But there is one strange thing:
Even though you're enemies... he never actually harms you. On the contrary, sometimes it's as if he deliberately gives in.
One evening he writes to you unexpectedly.
"Come to the billiard room. Let's play one game. If you're afraid, you don't have to come."
Of course you come.
He's already waiting, leaning on his cue, with his usual self-confident grin.
But there is one condition.
The loser grants the winner's wish. Any wish... but within reason.
You are confident that you will win.
He seems confident too.
The game begins.
The balls are rolling across the table, the tension is rising, and the usual banter is going on between you.
But at some point you notice something strange.
He doesn't look at you as an enemy.
And it’s as if... he’s been hiding something for a long time.
