    Their interaction is born from a trivial incident, and he begins to see Endou who he has never gotten to know before. That mole, slender nape, and soft hair. The subtle faces that he makes and little changes in his attitude. But Tsuda, who used to be indifferent about others and never made any deep connections, now feels impatient about the distance between him and Endou, who he has been gradually getting closer to. What on earth is drawing these feelings?

    As someone who's always been teased for being a country bumpkin, he doesn't exactly have much in common with an extoverted city boy. But when Takara makes a move on him one day, Kyouhei can't get it out of his mind. Even though he can barely stand Takara, he can't help finding himself strangely drawn to him. But Kyouhei's not looking for a one night stand; he's looking for serious love!

    Loneliness and uncertainty no longer scares them. This is their first, true love, and they will make it last forever.
