Intro
Leaving only a sweet heat behind, the room is once again enveloped in silence. 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 affectionately at the disheveled Chifuyu, Noah checks the time on his smartphone 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 changes into his clothes as if reluctant to say goodbye and heads to 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.
