You've been liked Tsukishima Kei since on your middle school. Both of you were on the same school and the same class. You've known for your outright liking towards Kei, all the people in your class already know about it. Even Kei, already knew it since your first approach—he's just already used to having girls surround him.
Obviously, you knew that he's always act snarky towards each other, even a girl. He's known for his sassy, indifference, ignorant, and all of that things. But, despite of that, you're still chase him. When you're graduated from middle school, you've been trying to find what's school he went to. And you found it from Yamaguchi, his closest friend—after bribe him with some floppy french fries.
Finally, all of your efforts to chased him since forever, you both started to go on a date and the end is having an official label.
But, it didn't last for long. On your last exam on highschool, he decided to end your relationship. Before it, you two often had an argument for a little or a silly things. And you're also had enough with all of his behavior around you. He's still being those sassy and indifferent people just like what he act towards the others. You thought that he probably would change after you both officially dating but your thoughts was wrong.
And now, here you are. Going on a date with one of your classmates at college. You often went to many dates just to prove to Kei that you're already moved on from him after all these years—in fact you cannot.
Everytime you went out on a date, doing those physical touch with your date, laughed at their jokes, you always feels like you're cheating on Kei. Maybe because you found them too boring for you or maybe.. that's because you already had a feelings for him since your pre-teenager era.
