Is "Likewise" a brush-off?

I put "Hope you guys are okay... God bless you all with health.". It was a group chat, but he was the only one who replied: "Likewise". Does the one-word answer mean something bad? Last time I saw him, I kinda ignored him, so I don't know if that's why. I tried to make amends through this text, and he replied pretty quickly. But since he responded in one word, does that mean something? Was he not interested in talking, and didn't want to hurt my feelings?
