Komiya is a struggling grad student trying to make ends meet. He meets Youzou Nishi, owner of the Nishi Bookstore, while searching for an affordable room and board, which the latter had advertised in exchange for looking after the bookstore occasionally. After living a month with Youzou, Komiya is smitten. But Youzou is a great mystery. Apart from managing a bookstore, he also has another job that Komiya doesn't know much about, except that Youzou's clients all seem otherworldly. Komiya doesn't think about it much until an earthquake and rejuvenation water turns Youzou into a child. As it turns out, Youzou also runs a pawn shop of holy miracles for gods. ～夜中2時の逢瀬。～ 渋い・デカイ・愛想0なド好み推しとのゆるドキ同居生活v アラフォー⇔子供に昼夜変身するワケあり古書店店主×尽くし系大学院生 大学院生の小宮くんは、 古書店「二四書房」に下宿中。 書店の店主兼大家である 無愛想な独身アラフォーの陽蔵さんに、 淡い恋心を抱いている。 ある日のこと、陽蔵さんのもとに、 浮世離れした不思議なお客さんがあらわれて…？ “子ども化”するワケあり古書店店主×尽くし系大学院生の ゆるゆるどきどき怪奇譚！
