This is actually a really solid volume.

Yosida finally has a dinner with Airi and she admits that she likes him. This kind of annoys Yoshida, but he also finds out she's a virgin when he asks if she would sleep with him. Making the situation awkward but least somewhat interesting. Then Airi wants to come home and meet Sayu after finding out Yoshida is taking care of her.

This brings probably the strongest part the last 3rd which gives new insight to both Airi and Sayu. Giving us reasoning of why she ran away and also a goal of what to do next in her shitty situation. It's great, and opens up some cool storytelling possibilities.

The opening with Sayu outgoing friend, Asami is a bit iffy. It's just over the top and silly but it has some good lolz moments.

Overall, enjoying this manga more than I thought I would. A 4 out of 5.
