Also known as: HGに恋するふたり
Manga series by Kudou Makoto, published in Gundam Ace. The series follows an Office Lady named Kanzaki Sayaka (HG Ni Koisuru Futari) and a high school girl named Takamiya Sora, who quickly connect over their shared passion for Gunpla models. It focuses on the leads' bonding over their shared hobby, experiences with the Gundam franchise, and having someone to talk about those interests with for the first time.
The series is heavily influenced by the mangaka's own experience watching Gundam SEED and Destiny when she was younger, as well as her current love of gunpla.
It is set in the same continuity as Kudou's other ongoing work, Bukiyou Na Senpai.
