Yuu is a healthy high school student who harbors a crush for his Kyouko sensei. He absolutely loves everything about her and after fretting about the subject for some time he decides to confess; to his surprise Kyouko Sensei is also in love with him and agrees to date him.<br /><br />.... The catch is that Yuu doesn't know why Sensei is in love with him, neither he knows her preferences when it comes to how to behave to her partner....<br /><br />And by the time of when Yuu learns this we have that "Yuumi" is born, now Yuu doesn't know if he should somehow enjoy his new relationship or regret it. <br /><br />Same author of Amaharakun-plus.
