This is a remote town with a milk tea shop called Lucky.
Lucky is always open, open for long hours, serving students, couples, people taking a break, and late-night passers-by, and I am the only night shift waiter here.
Weird things always happen at night, such as ghost guests, mysterious sanatoriums...
Fortunately, the elusive regular Mr. Stone always shows up at the right time.
