Question about this example sentence:
この足跡が気になる。もしかしたら熊の足跡かもしれません。
気になる is in casual form but かもしれません isn’t. Is this a mistake or is 気になる a set phrase that doesn’t become 気になります?
This is a very late reply, but I’ve seen 気になります used by native speakers, so it can definitely be used in the polite form aswell!
I’m not sure why it isn’t used in the example sentence though.
