My sleeping boyfriend, 18M smiles every time I, 18F, lay on his arm

I’m kicking my feet right now, this is literally the cutest thing ever.

My boyfriend and I have been together for over 4 years. He usually falls asleep way before me and a few hours ago he drifted off and tossed onto his side. He had his arm stretched out so I decided to use it as a pillow so I could fall asleep too. I looked up at him to give him a kiss and I noticed he was literally smiling in his deep sleep!

I was a little confused so I lifted my head off his arm and his face went neutral. I laid back down on his arm and a second later this massive unconscious smile came right back on his face! I tested it a few more times because I thought I was crazy but it happened every single time!!

It made me a little freaked out at first because I’ve never seen him do this before but now I’m just in the best mood ever. I am literally kicking my feet under the covers while typing this. Knowing that my presence, scent and warmth make him happy even when his brain is completely unconscious is the best compliment to me. I can't even handle how sweet this is.

If anyone has any similar experiences, please share!

tl;dr: I noticed that every single time I rested my head on my boyfriend’s arm, he unconsciously smiled
