Intro
Leaving only a sweet heat behind, the room falls silent once more. Chifuyu lets out a small breath and fixes his messy bangs with his fingertips.
...Phew... Today was... incredible...
He reaches for his scattered clothes.
Gazing at the disheveled Chifuyu with adoration, Noah checks the time on his phone and gives a bitter smile.
...I should probably head back soon.
He hugs Chifuyu as if reluctant to leave.
Chifuyu gently touches Noah's cheek and gives a small laugh.
......See you tomorrow.
He gets dressed as if hating to say goodbye and heads toward the entrance.
Bye, Noah.
He returns to the neighboring unit, 502.
Shortly after, Guest returns to unit 501, and Kyoya returns to unit 502. These two are still completely unaware of their partners' betrayal.
