Gunjouiro no Yoru wo Kette

At his high school entrance ceremony, Genta couldn't stop thinking about Yuki, his childhood friend he had grown distant from. No matter how hard he tried to fill the emptiness with new friends and skateboarding, all that remained in his heart was regret. If only he could go back to that day, he wouldn't have avoided him. Meanwhile, Yuki also regretted what had happened. He was haunted by the memory of Genta's bewildered face when he had almost kissed him, unable to hide his feelings any longer. Bound by bittersweet emotions, what awaits the two who still think of one another...?
