So I was reading this manga series and I got this really intense feeling from it, that I had to put it down. Could these be kinfeels?

It could be kinfeels.

It could also be that the story simply hits you in a particularly intense way.

It could be that the story relates to your life now. Or it could be a big wave of empathy.

It could also be that you were feeling emotional when you read it.

Or it could be kinfeels; but not kinfeels for that story. Just that the story reminded you of things that happened in another kin life.

Intense story feels or character feels aren’t always kinfeels.
