Fushimi likes to sleep/lay on his boyfriend's chest and listen to his heartbeat. Yata loves this position because he can kiss the top of Fushimi's head.

This being the only time Yata can reach to kiss the top of Fushimi’s head, of course >:D I imagine Fushimi being kind of clingy anyway, like he won’t admit that he wants to be close to Yata but I can totally imagine him just flopping on top of Yata without a word. Like Fushimi will get home from work and Yata’s laying on the couch or sitting on the bed and Fushimi just climbs right on him. Yata gives a small protest like geez Saruhiko it’s a good thing you’re not very heavy you know, I need to breathe here. Fushimi just grumbles that he’s cold and Yata smiles all right I better warm you up then. If Yata tries to move Fushimi will get all fussy so he has to resign himself to sitting there with his boyfriend resting on him, Yata figures well there are worse things than getting to be Fushimi’s pillow. Fushimi always falls asleep with his head on Yata’s chest too, like the sound of Yata’s heartbeat is soothing to him (he won’t say it, but Yata knows that Fushimi likes it because as long as he can hear Yata’s heartbeat he knows that Yata is there, that Yata won’t leave). When he starts to get drowsy Yata will tell him it’s okay to just sleep if he’s tired, Fushimi says he’s fine but of course he doesn’t move. Yata kisses the top of his head gently and Fushimi just relaxes on top of him and that’s the best part for Yata, seeing how Fushimi, who so rarely relaxes around anyone, just completely drops his guard for Yata.
