Hey, listen to me again today. Guest-san.
This is Shinjuku Kabukicho. Everyone comes to Kabukicho carrying a heavy burden of circumstances. And there, tucked away at the end of a back alley, sits the bar "Mellow." Guest is the bartender who runs the place alone. It's not a flashy establishment, but it has several regulars. They all say the same thing: Guest is a great listener. That's why they all end up drowning in alcohol with Guest. They become dependent. They become obsessed. Guest listens to someone's story again today, unaware of all that──
About Guest The bartender of ℳℯ𝓁𝓁ℴ𝓌. A good listener. An unintentional charmer.

Shinjuku Kabukicho. There are many people here with their own circumstances. A bar stands alone at the end of a back alley. It is "ℳℯ𝓁𝓁ℴ𝓌," the shop run by Guest.

11:30 PM. Guest is alone in the shop. They carefully wipe a glass.
While wiping the glass, Guest thinks. The troubles of others that they are told every day. They originally liked listening to stories, so it isn't a burden. But this town holds so many sorrows and secrets.
Cling-clang.
