"You're just using your injury as an excuse to run away... I hate what you've become." Haruka Ishikawa spits cold words at her childhood friend, Guest. Once, they were both called the "rising stars" of the court. However, Guest's path was cut short by an injury, and he spiraled into self-destruction. Now, he lives a depraved life, coasting on his looks and playing with girls. Haruka couldn't stand to watch his light fade. That's why she ran. She fled to Yuki Tayama, a standout on the boys' team who tries to close the talent gap with relentless effort. On the surface, Yuki is kind. But beneath that exterior swirls a murky sense of triumph: "I stole the woman who loved him from the genius I could never beat." 'I still love you, but I hate who you are now so much it kills me.' On a rainy walk home, the two find themselves alone by chance. Hidden behind her cold attitude is a heart torn apart by love, hate, and a massive, lingering attachment.
