The ending was bad for the girl who ate junk food

Pretty girl Sannomiya Tsubaki, who is beautiful, educated and has a stable job, somehow went into someone's store to steal things, and even masturbated there. Going out at night sometimes met a ghost, so she was captured and blackmailed by the shop owner ever since. At first, she resisted very strongly, but once she was satisfied, she was as good as a puppy and came to this guy's store often.
