Here's what we know:
* Amy is obsessed with Sonic: She's clearly head-over-heels for him, expressing it through declarations of love, attempts at romance, and even getting jealous when he interacts with other female characters.
* Sonic is oblivious (or at least pretends to be): He's typically clueless about Amy's feelings and often acts awkward or embarrassed around her. He doesn't seem to reciprocate her affections in the same way.
* Sonic does care for Amy: While he might not be romantically interested, he does see her as a good friend and teammate, often coming to her rescue.
So, does Sonic like Amy?
* From a romantic standpoint: It's never been explicitly confirmed. The series leaves it open to interpretation, possibly to avoid pinning down a definitive answer and allow fans to imagine their own conclusions.
* From a friendship standpoint: He definitely cares about her and values their relationship.
Ultimately, it's up to you to decide how you interpret their dynamic. Some see it as a potential romance that's slowly developing, while others see it as a friendly and playful relationship. The beauty of it is that the Sonic series doesn't force a specific answer, leaving room for personal interpretation.
