Kisumi enjoys teasing Haruka a lot. For example, whenever he ants a kiss, he’ll just ask Haruka to say his name and pretends the boy says the english word ‘Kiss me’ and kisses him. Haruka falls for it every time.
Kisumi still finds it funny to feed Haruka, but Haruka refuses to do that ever again with the other since what happened in highschool.
Haruka isn’t affectionate towards Kisumi, but sometimes does feel like giving him a quick hug. This takes Kisumi by surprise and very happy, saying how cute the other is. At this, Haruka mostly let immediately go.
