hoping someone can point me in the right direction
i'm looking for the manga from the cover of this magazine
https://www.amazon.co.jp/%E3%82%AB%E3%83%81%EF%BC%A3%EF%BC%AF%EF%BC%AD%EF%BC%A9-vol-21-%E9%9B%91%E8%AA%8C-%E6%B5%85%E4%BA%95%E8%A5%BF-ebook/dp/B07Q37GXBC/ref=sr_1_41?__mk_ja_JP=%E3%82%AB%E3%82%BF%E3%82%AB%E3%83%8A&keywords=%E5%90%8C%E6%A3%B2%E3%83%A4%E3%83%B3%E3%82%AD%E3%83%BC+%E8%B5%A4%E6%9D%BE%E3%82%BB%E3%83%96%E3%83%B3&qid=1575410080&sr=8-41

thanks!

On the lower left corner there is illustration: Shoowa I believe that's the author, not sure which manga tho

The third page in the amazon preview which looks like the table of contents under the SHOOWA entry on the top right says 同棲ヤンキー赤松セブン which is Dousei Yankee Akamatsu Seven maybe it's that one?
