Chapter 2: Last Time In Universe 7...
"Well, we'll miss you, buddy," Goku said giving a pat on Yamcha's back...but gently of course since he didn't want to hurt Yamcha. He'd miss the guy, especially since he's one of his oldest friends. But if Yamcha could actually become stronger through this, then Goku was all behind it.
Bulma approached Yamcha. Even after they parted ways and she went on to marry Vegeta, she still cared for Yamcha's safety. Sure, she berated him for being an idiot. It's partly why they broke up. But she had come to consider him a good friend even after all these years. "You take care of yourself, ok?" She said.
