The ordinary and competitive me, along with the perfect honor student Komaki, decide to wager something important in a challenge. "The one who feels good loses," and even the precious kiss becomes part of the competition. However, I find myself feeling comfortable with the interactions with Komaki, and thus I end up losing a week of my summer vacation to him. "Make sure to engrave it in your memory. So that no matter who you date in the future, you can remember me." From the pool to the aquarium, and even an overnight stay at a hotel. While I dedicate an ideal date as "a couple," I also feel lonely knowing that I don't know Komaki's favorite things or his true smile... And at the end of the week, the summer festival arrives. Will the fireworks illuminate Komaki's feelings?
