Loki shows you he loves you in the way he...
(i suppose i put off posting this for long enough)
cradles your head close to his chest when he hugs you after a long day. when it's been especially tiring, he likes for you to lay on top of him while he does it, for extra sense of security. it also provides perfect access to kiss the top of your head
puts extra care into the things he does for you. when loki makes food, he takes time to pour his affection into it and make you feel appreciated. same goes with tasks you ask him to do because at the end of the day he just wants to make you happy and see your face light up
listens when you ramble about even the most insignificant things because to him, it shows how you long to talk to him even when it's not "necessary". he loves that you feel comfortable talking to him, and doing it without thinking makes him feel like the luckiest in the world
looks at you like you're the answer to every question and quarrel the universe has ever presented
holds you tight in bed while the world moves outside and showing you there's nothing he loves more (other than you yourself) than being close with you <3
