Family Simulation!! by Matsuyoshi Ako [Eng]

Plot Summary:

Graduate student Asahi’s life takes an unexpected turn when he suddenly becomes the caretaker of his five-year-old nephew, Masaki. Struggling to make ends meet, he finds himself barely able to afford groceries—until a chance encounter at the supermarket reunites him with his childhood friend, Sora, after six years.

Seeing Asahi’s struggles, Sora offers to help and soon moves in with them. What starts as a makeshift family dynamic gradually shifts as Sora becomes increasingly affectionate. As their closeness intensifies, Asahi finds himself flustered. “D-Don’t! Masaki’s in the next room…!!”

Is this just a friendly arrangement, or is something deeper beginning to bloom between them?
