Hearing Asgore flourishing his practice trident after removing it from it's home on the rack before training and receiving a minor adrenaline kick from what I assume must be a Pavlovian response to the unique swooshing sound it makes, sweating buckets helping out Asgore with some gardening in the intense summer heat when I ask how he manages to keep cool since he doesn't sweat and I've never heard him pant like a dog or anything despite having all the fur (felt a bit rude after I said it honestly) to which he responds that the heat simply doesn't really bother him and that he just drinks cold water if he's hot, studying for an important upcoming exam with Asgore sitting on the end of our bed reading out questions from the textbook in his lap and either congratulating me with a big smile if I'm right or helping me find the correct answer if I'm not (I kiss him lots afterwards and tell him I don't deserve him)
