The idea I had for this one was to have Gohan comfort Videl after some stupid girls bad mouthed her (because they're jealous, of course). While Videl always keep a tough exterior, she is still a girl and those mean comments about her life and looks hurt. Gohan goes after her and comforts her, most likely saying that she doesn't need to do anything to be pretty, unlike those girls who don't compare to her no matter how much they worked on they physics anyway. And that's Videl's reaction

("You... You really think so?")
Might be OOC, but I like to think that it's not ^_^
I think it fits since I believe Videl trusts only Gohan enough to see her more vulnerable side without making fun of her.
