What a beautifully cute story! Thanks for translating this! There arent too many bulma and vegetta stories that gets translated even though there are many out there for the two. They do care for each other, and vegetta does love her, especially since they even had another kid together, Bra, so having Trunks wasnt just a moment of passion or a mistake. If you even look closely in Dragonball GT there were some pictures and a flashback scene of Vegetta taking care of Bra when she was a baby lol.
