Something was very wrong

Sam wasn't trying to curry favor with anyone, nor was he making a deliberate effort to shower Sophie with attention. 

In Sam's eyes, matters of the heart were straightforward: as long as he had no regrets about his own efforts, why should he care about others' mockery or misunderstanding? 

Ultimately, the only person one can truly be accountable to is oneself. And the only one who can truly understand your affections, your persistence, and your unreserved dedication is you.

Of course, what Sam did on the roller coaster was quite simple; he merely didn't want Sophie to face any trouble that could leave a deeper scar. 

So, he did something seemingly minor, perhaps it could be considered tender, but it was hardly worth mentioning. At least, he never thought such a gesture would cause any significant change.

When Sam returned with water for them, he could clearly see Sophie casting a complex glance his way before quietly accepting the bottle.
