Dan Heng knows love because he knows you. It's a very simple concept, really.

His name isn't inked on your skin, like soulmates are, but he feels that pull. He knows your souls are intertwined.

"You never get tired of this?" Dan Heng murmurs quietly, his forehead rested against the back of your shoulder. You're brushing your teeth at the moment, something part of your daily routine.

He'd helped you countless of times work on self-care; warm rose baths, skin- care movie nights in the archives, him helping you stretch after sitting in an uncomfortable position after working for long periods of time, massaging your back and your feet. (despite how many times you complained about feet being gross, Dan Heng never complained. he couldn't refuse you, not when you were working yourself half to death)

You get up at the same time every day -- 4:30 am -- and go to sleep (with his coercion) every night -- 11:45 pm. He has your entire schedule engrained into his being, as you are. Dan Heng glances to meet your gaze in the bathroom mirror before pressing a kiss to the side of your head.

Dan Heng loves you -- that much is certain.
