Explaining Love To A Sergeant

Sousuke Sagara and Kaname Chidori: two people who couldn't be any different if you tried. And yet, there was something between the two of them, which was especially obvious to everyone BUT them... until just recently after the events of The Second Raid. Some time after realizing this, Kaname has "issues" trying to get Sousuke to understand love, much less do any of it.
