Frenemy

"There aren't two suns in the sky... or are there?!" On his first day as a transfer student, the tennis genius "Kang San" who has drawn the attention of the world meets "Joo Shin-ee" who plays tennis as a hobby. What began as a light-hearted request for a match ends with the first humiliating defeat for "Kang San". And with that "Kang San", who had been maintaining an undefeated streak thanks to his natural-born talent, had his puffed-up pride completely deflated. The power player "Kang San" who uses his strength and speed to crush opponents! And "Joo Shin-ee" who uses his resourcefulness and control to exploit his opponents' weak point! Two very different kind of geniuses have met! Who will come out the victor in their match "1 year later"?!
