Asahi is a graduate student, who suddenly had to take care of his older sister’s child Masaki. (5)
He was shopping for dinner in a supermarket. Troubled by his tight living expenses, he coincidentally met and received assistance from his childhood friend Nishino, who he hasn’t seen for 6 years.
The family of 3 men just happened as they went with the flow, but somehow Nishino’s skinship is
crossing some lines?

No, you can’t! There’s a child watching us?!
