Maybe this story will be Jihyun and Chiwoo. The two of them will be a couple at the end of the story and that Kouhai will be with someone else. Here in this story, Chiwoo will realize how he really loves Jihyun and thus, they ended up together. Hahaha My ideals
I think Keita purposely sped up cycling because he wants Kanata to hug him from behind like a couple. How cute (=・ω・=)
