Machi to Hito no Romansu

From the Animeraider: This is the tale of Yuriko, a young girl looking for romance who starts to fall for a boy named Shouta – who bears a striking resemblance to the first love of Yuriko’s single mother… The volume also contains the titular story's sequel, "His and her Summer" (Kare to Kanojo no Natsu). *Note: In 1991, it was compiled (under a two-in-one format) with Stardust 3-Nenme, released by Shueisha Girls Comics.*
