No, she tried to pull out the training afterwards. Because she didn't want to flunk and disappoint Fuutarou. Typical Yotsuba, doesn't want to try the direct approach because that'd be acting against her sisters but deep down she still hopes she can get Fuutarou 's attention by acting good.
Same thing goes with the 'there's no way it'd happen, she was hopeful because of her classmates comments but was too afraid to ask directly so she tried to avoid the issue. When Fuutarou pried it out of her mouth she tested the field to see if he had some sort of affection for her.
That was a bad move, be a use Fuutarou being Fuutarou there was no way he'd respond in a tactful way.
