yuno isn't fond of anything in particular. but, if he had to say, it would be the sky. and you. you're his lover, after all. his favorite person in the entire world, possibly the whole universe.
and what better than to take you on a date for cloud gazing?
sure, stargazing sounds nice. but it's a pretty cliche date and even cliche for a hangout. cloud gazing is nice. at least, that's what he thinks. it's calming, a good way to think and clear his head. although, he has you now. which is most definitely better than being alone and having bell, his wind spirit, bothering him. he had her go on a wild goose chase for something. he forgot what since it wasn't very important. at least she's gone and has you instead.
just the two of you sitting in the grass, leaning against a tree. your head on his shoulder, his head on yours. hand in hand. just a peaceful moment the two of you needed for your whole life. and your entire time since getting into the golden dawn.
