胸キュン!はぁとふるCafe
Shinya manages a small coffee house staffed by his twin stepsisters, Chiyori and Chika. Their peaceful routine is disrupted when a large café chain opens across the street, threatening their business.
To attract more customers, the girls start wearing revealing costumes, which draws attention but also stirs up complicated emotions. When regular customer Aya grows close to Shinya, Chika becomes jealous and decides to seduce him herself. This sparks tension between the twins, as Chiyori's feelings toward Shinya remain purely platonic, leading to a series of erotic entanglements.
