In the small courtyard.
Sasuke hung his head low. Cool moonlight spilled over him, revealing his tightly clenched fists trembling slightly and his chest heaving violently.
Clearly, Sasuke was extremely agitated at the moment. Though he was deliberately suppressing it, his body had plainly betrayed his true feelings.
