Family Simulation!!

Asahi, a graduate student, is suddenly responsible for his five-year-old nephew, Masaki, after his sister's absence. Struggling financially, Asahi meets Sora, a childhood friend, at a supermarket. Sora, despite no contact for six years, offers assistance and moves in with them. Their shared living arrangement starts as a practical solution but becomes complicated as Sora's behavior grows increasingly affectionate. Asahi finds himself in awkward situations, especially when Sora's actions occur while Masaki is nearby. The manga includes two works: one focusing on this domestic scenario and another titled "I Love You At The Micro Level!!."
