Sharing the bed. There's nothing more romantic that letting yourself vulnerable just falling asleep by their side. I love to imagine them cuddling (Torao is the big spoon) just talking with each other about mundane stuff until one of them falls sleep first... I HC both of them with insomnia (Haruka specially gets to have a very bad one) so they can be in bed for hours just talking until one falls asleep first (Haruka usually) and that's just peak romance
