Cheelai & Yamcha hugged each other in enjoyment realizing that they survived,until they realized Goku wasn't coming back.They helped gather the Dragon Balls,until Goku said he wanted time to train.Instead of wishing for Goku to come back they wished for 18 to be a human & 17 to be brought back as a human.Yamcha told Cheelai it was time to break the news to Chichi.Cheelai said it would've been best if she told her,Yamcha agreed he carried her to Chichi's house.She walked into Chichi's house & told her that Goku had died,Chichi broke down in tears Cheelai & Gohan comforted her.She walked out saying it was sad but Goku will be back soon enough.She asked him if he meant what he said about her going to college,Yamcha blushed a bit saying yes.
He flew her home & celebrated by having their honeymoon,Yamcha got back into Baseball & he went to college as well to become a professional cook.He used his baseball paycheck to pay bills & her college fund.She was aiming to be a scientist like Bulma, but also be strong like Yamcha(LOL).During the day they went to college & during the night they trained in The Hyperbolic Time Chamber.She did eventually get bullied for the color of her skin,& hit on her until Yamcha told them to back off.After 4 years of college the both of them finally graduated,Cheelai did become a Scientist(on the level of Bulma).They both got stronger as well,Cheelai decided to build a training room(Imagine a Gravity Room you can get a year's worth of training).She eventually asked Chichi to teach her how to cook.
After a month she learned,Chichi gave her a pack of a green variation of her(Chichi's) clothes.Though she only wore them when cooking,she wore her science clothes(basically DBS Bulma Science clothes) when she was working on the training room for them.After one night of training Yamcha had trouble asking a certain question.Until Cheelai asked him that question with a wink(basically if he wanted to have,intercourse I'm going to timeskip for obvious reasons).6 months after that day,Cheelai & Yamcha were in a hospital where she was holding a baby girl. She had decided to name her Cheecha,Cheecha had Cheelai's green skin & white hair Yamcha's face,and they showed her to everyone.They all congratulated them except Bulma,3 years passed & something was about to happen.
