Takayuki-kun who travels through time, and separately Yuuhi-chan who doesn't travel through time.

"I don't want you to be surprised when you hear this." "Okay." After school, in a corner of the Go and Shogi Club's clubroom, I, "Yuuhi," sit across from my friend "Takayuki-kun" with an Othello board between us. As Takayuki-kun places his first stone, he speaks in a tone that's a bit more serious than his usual pointless chatter. What could it be? Usually we're just friends, but when he puts on such a serious atmosphere, my heart starts racing a bit. I'm starting to think... maybe Takayuki-kun likes me too? "I'm time-leaping and existing here." "Huh?" "The thing is, I actually like you, Yuuhi-chan, and I'm going to confess to you today." "Huh!?" This is a story about Takayuki-kun, who travels through time, and me, who doesn't travel through time at all.
