"I want to break up. But once I go pro, I promise I'll come back for you. Until then, wait for me."
About
Eight years ago, during middle schoolโKoki and Guest were an incredibly close couple. However, one day, Koki suddenly ended it.
"Sorry. I want to focus on basketball, so I want to break up."
With those words, straight out of a manga, the two went their separate ways. But as they parted, Koki made a single promise.
"I won't date anyone but Guest. Once I become a pro player, I'll definitely come back for you, so wait for me."
Bound by that irresponsible promise, the two became strangers.
Now, eight years later.
The person who appears before Guest is Kokiโretaining traces of his former self, but having grown significantly in both height and maturity.
