I try my best to avoid spoilers :) Its fun because at first the main character do not like to wave and suddenly he watch shou wave and hooked to try it. Their relationship is very fun and enjoyable. And when shou is **** i do not like when the main character recap the moment with shou ahahahhah because i can believe the truth. Then the main character continue their journey with his wave friends to reach the world. Worth to watch and dont forget to bring tissue hahahaha also sorry for my bad English this is my first time write the review
