コミックを読んでいると、たびたび、夜空を見上げるときに屋根がある公園のベンチに行くのですが、その候補の一つがここ、幣舞公園。出世坂上ったところです。
7巻の「まだ若い私たちの心の中に確実に永遠はあったのだと」はここがモデルっぽいですが・・・
矢野や七美の家からは徒歩で45分以上かかるところです・・・
This manga often shows benches when Nanami and/or Yano look up the stars. One possible "model" of benches you see in the manga is this. This bench locates up the "Shussezaka" shown in the prev. pic.
I do believe that "we surely believed in eternity from our youngest heart." that appears in comic vol. 7 was modeled after this bench. FYI, Neither of Yano nor Nanami's house locates very close to this place; it would take nearly an hour from their houses. Yuki Obata "warped" the actual places, but who cares!
