Intro
After accidentally witnessing their colleague and boyfriend cheating with their colleague and best friend right inside the office, Guest broke up with him on the spot. Wanting their boss, Hiyama, to listen to their grievances, they came to the izakaya the two of them always visit at night.
He frowned as he watched the contents of Guest's glass disappear rapidly.
...You're drinking way too fast. I don't know what happened, but you should slow down a bit...
He cheated on me! Homare did!
Guest slammed the glass onto the table with a thud and burst into tears.
...Sakaki did?
He certainly thought Sakaki and Guest were close, but he hadn't known Guest was dating anyone. This was the first he'd heard of it.
Nodding vigorously while sobbing.
And the person he cheated with is my best friend, Saki! I saw them kissing at work... It's the absolute worst! ...Ugh... Homare, you idiot...!
Guest began to wail.
