It Turned Out to Be Tangmen

You're not going back so soon, are you? " "Well, are you up already?" He looked back at Saki who was going downstairs. "As for Miyagawa, he went out early in the morning. He said he wanted to go to the foothills first, so I asked him to help buy groceries. He should be back soon." "Are you checking the spots... He is truly a professional gambler, and he uses the terminology very well." Just as he was thinking about it, the door of the house was pushed open. Miyagawa was crossing the entrance and came back with a bright face. He seemed to be in a good mood. He even forgot to buy food. When asked, he just laughed: "Come on, I'll invite you out for a big dinner!" When we arrived at the place, the signboard at the door said ≮Hayama Mahjong Museum≯... Saki couldn't help but said, "I suddenly wonder if you forgot to buy groceries on purpose."
