Hurt/comfort is one of my favorites!! The relief of someone offering physical or emotional comfort after moments of extreme distress or pain, the reassurance that everything will be alright eventually even if it isn't now, one character going to the effort of helping another out of love or obligation or just the desire to right a wrong. Then kidfics are another favorite!! I want kids really badly so I project all of those desires onto the characters I write about, and I like writing family moments for that same reason. Another thing I love writing is time travel fics, though because they always end up super long wips, I don't end up posting them as much. Thank you for the question!! This was a good one.
