[Aoba Momiji] Kaisha no Madonna-teki Sonzai to Ichiya Kagiri no Kankei ni Naru...

I'm usually skeptical about ppl commenting on retracing other works but you two are really onto something here and I second that as well.

pretty sure bro retraced his art from that

For some reason it feels like it's imitating the art from the guy of silent war. It's specially noticeable in the last 4 pages, I almost thought the guy was giving a go at doing manga but no, it's a different guy. Although the cover it's missing, so might as well be our guy and the page is lying.
