Very well. Thought you might, since there are "reunion" works in your list. Tends to be the case very frequently. And kind of makes sense. If they were together every day there's little threat of change, and this can make it far more comfortable to simply stay as you are.
If you're fine with younger characters some volumes of Naisho no Tsubomi would qualify (I'd have to look back to find which do and don't, since every volume is a different story with different characters). Also pretty sure another of the author's works, Mizuiro Jidai, goes this direction.
Asagiri no Miko also fits the bill (though I don't know if anyone will ever translate it).
Love Rush, Misoshiru de Kanpai, Hatsukoi Zombie (sorry reunion series), Ginen Shounen (one of my favs), Joyful Days (oneshot), and Karakai Jouzu (?) no Nishikata-san (also reunion) also fit.
