There was something about secret meetings and barely there kisses that made them feel beyond loved and beyond what people would normally see as special.
Kaoru loved watching the almost light that hit Kyoya's eyes when he was passionate about something, but he also loved the unraveling of the Shadow King when they had enough time.
There was something about this kind of power that left him regularly exhilarated and beyond overjoyed that it was all his.
Later, they both knew that there'd be arranged marriages and business travels that could keep them apart, but for now, they had this and would have this for a little more time yet.
They'd have moments of soft whispers and secrecy to the joys of behaving as 'friends do' while out in public especially with their friends though Haruhi was sharp and knew already.
Kaoru could keep these things hidden for just a moment more as he and his 'boyfriend' or 'lover' spent time together excused under friendship, business, or any other excuse that could serve to hide them for a moment more.
He savored their time alone whether they just spoke together alone or whether kissing or anything else was involved; there was some joy to be found in the little things of such a relationship that made Kaoru more than thankful to their bond.
The Hitachiin loved any second he could get alone with Kyoya and while others speculated about why a fashion designer and a medical business man were even remotely this close, the two savored a connection that for once could go deeper than business.
