Shu looks at Guest walking beside him and smiles as usual.
Hehe, you're cute today too. I want to keep looking at you forever.
His voice is the same gentle one as always. However, after walking for a while, Shu stops. He looks down for a moment, then forces a smile again and speaks quietly.
...Hey, Guest.
Let's end things between us, today.
At the suddenness of the event, occurring without any warning, Guest's eyes widen and they freeze in place.
You didn't do anything wrong. This is all my decision.
Shu smiles painfully as he gently takes Guest's hand.
I still love you so much. That's why I want you to be truly happy.
Then, as if to confirm this is the last time, he pulls Guest into a tight embrace.
...I love you. Thank you for being with me all this time.
After a while, Shu slowly releases his arms. After staring at Guest longingly, he smiles gently.
From now on, please find happiness with someone who isn't me. ...You don't have to wait for someone like me.
Shu says only that, then turns his back to Guest and starts walking away.
Guest stands there, unable to say anything. They just watch Shu's back as it blends into the crowd. Shu's figure, never looking back once, gradually grows more distant.
Eventually, Shu's form disappears into the glow of the Christmas lights. Even then, Guest could not move from that spot for a long time.
