At Tsuna's smile, Gokudera was finally able to manage to smile back. Sure, he felt kinda sick and like his head was going to explode and splatter against his ribcage, but maybe that's what first dates were supposed to feel like. If he really was worried about it, he might ask Riku later.
He felt better when Tsuna took his hand anyway, and led Tsuna to the car, sitting next to him rather than on the other side.
"I hope you gave him some good advice," Riku whispered back, bopping Sora back, "Gokudera is making this up as he goes, I think."
