A brief tidbit in a Dr. Slump Volume, (A Manga by Akira Toriyama) number 16. His exact quote on the page;
"The truth is, there's no deep meaning behind Senbei and Midori getting married. I didn't have anything in particular to write about that week, and figured it'd be fun. Since I can't stand love and romance, I didn't want anything long and drawn out, so I just had 'em jump right in.
Incidently, my editor, Mr. Torishima, loves love and romance, which is a problem. Akane and Tsuku-Tsun? Taro and Tsuru-Rin? Arale and Obotchaman? All Mr. Torishima's ideas. Frankly, writing romance gives me hives. Movies too--when they get all sappy, I shut my eyes. This is a secret, but in the other manga I'm writing now, Dragon Ball, Mr. T wants Son Goku and Bulma to fall in love. Oh, great."
Also, here is something regarding Krillen which I found interesting.
Speaking of women who fight, there is No. 18.
Ah, that’s right. No. 18 becomes Kuririn’s wife in the end.
Ah, I was surprised at that, too! All the voice actors wondered, “Why did she choose Kuririn?” (laughs)
Kuririn was originally supposed to be just a minor role, so to have him become Goku’s best friend in the blink of an eye…
Well, he is the strongest Earthling male.
You’re right, he is the strongest among the Earthlings. But in spite of that, he tends to end up in a bad way, so I thought, “once in a while, I have to let him be happy,” and had him get married. (laughs)]
[AND YOU DECIDED TO PAIR HIM WITH ONE OF THE MOST BEAUTIFUL LADIES WHO KICK *** AND IS UNPHASED ABOUT EVERYTHING LIKE VEGETA?
NO WONDER HE CHOSE KRILLEN, HE'S COMPLETELY ABYSMAL WHEN IT COMES TO LOVE SO HIS MATCHUPS DON'T SURPRISE ME...]
