Here's a summary of what'll happen in the v-ball drawings.
Duo has challenged Heero to a volleyball match-up at a beach to see which country (between American and Japan) produces the best athletic talent.
Wearing flag swimsuits is Duo's idea. He wanted them to play each other representing their countries.

Duo heads to the beach, ready for the match and he decides to stretch out before the game. He sees Heero already there and calls out to him. Then he tosses the volleyball he brought to Heero. Heero holds the ball briefly and then walks up to Duo, ready for the match. Duo is really excited about the match and completely ready for it and he totally rubs it in towards Heero with his usual light-hearted attitude. Heero starts to stretch out and while he's doing that, Duo lobs the ball to Heero (who is caught a bit off-guard by it) and light-heartedly tells him that he can have the first serve.

Then the match starts, Heero and Duo are both faring well in the match-up and for a little while, neither of them can get the ball by each other. Then, Duo notices Hilde on the beach. He looks the other way and waves to her, when the ball hits him in the head and it results in Heero winning the match. Duo afterwards can't believe he lost so Hilde comes up to him wanting to hang out with him, so the two of them run off together.

When I get these drawings completed, the set will consist of several panels of drawings.
