What little things your boyfriend/girlfriend do that makes your heart go UwU or something?

I have never been in a relationship before so I have zero experience but of the many yaoi I've read, I at least think that the little things my boyfriend/girlfriend do that possibly will make my heart go UwU would be:
1. Them snuggling to me for warmth or them hugging me in the bed to make me feel warmer.
2. Them waking me up so I can eat the food they made for me. (I also like doing this towards my future partner since I'm more of the house husband type.)
3. Them letting me take a nap on their thigh while they stroke my hair/head while they are watching TV. (TV sounds in the background is oddly soothing when you want to try to sleep, at least for me it is.)
