Smile and Peko's friendship is the kind that destroys you because it's built on the exact thing that keeps them apart. The show moves like their rallies, patient, building pressure until something breaks that you didn't know was fragile. Masaaki Yuasa animates the ugliness of ambition and the loneliness of being talented in a way that makes sports feel like the smallest part of what's actually happening. This is not a show about winning a match. It's about two people learning what it costs to stop protecting each other.

Smile is quiet and reserved, while his childhood best friend Peco is loud, overconfident and set on becoming the world's best ping pong player. Both are gifted players on the Katase High team, yet Smile holds back his full strength against opponents. When Peco suffers a crushing defeat to Kong Wenge, a former Chinese national team player at rival Tsujido High, he begins to doubt why he plays at all. Meanwhile, Katase's coach sees Smile's potential and tries to train away his hesitation, but Smile has little interest in playing for anything but enjoyment. As both search for meaning in the sport, tougher rivals with struggles of their own wait at the inter-high tournament. The result is a psychological sports drama about friendship, ambition and the cost of chasing glory.
