The warm sunshine shone on Gu Lu.

Gu Lu opened his hands and let himself bathe in the sunshine.

Simon, who had fallen asleep on his desk, was awakened by the sound of Gu Lu pulling the curtains.

Simon raised his head in a daze, and subconsciously turned his head to look at the window.

Then, Simon's eyes suddenly widened a bit.

Because he saw...

Gu Lu turned into light!

Gu Lu noticed Simon waking up.

Gu Lu leaned on the window sill, facing Simon.

He raised the corners of his mouth slightly, with a faint smile on his face.

Gu Lu looked at Gu Lu with calm eyes and said softly, "Simon, I think it's time for us to add some spice to the peaceful mathematics world!"
