[Machine Translation] Sophia has been accepted into the baseball club that Kento belongs to. She was thinking that she would be able to close the gap between her and Kento, but the rules of the baseball club prohibit romance in the club...? Sophia must not let her feelings for Kento be revealed to the club members. Sophia, who has become overly conscious of this, suddenly finds herself unable to grasp the distance between her and Kento. Sophia, who still wants to be close to Kento, decides to call him "onii-chan" in order to be with him as her "little sister"...? Nadeko, who couldn't bear to see Sophia like this, suggested that they have a sleepover at the Shirakawa house...? The third act of this romantic comedy is a little too cute and sweet for the British sister-in-law who can't be honest with Sophia.
