Progression of plot: Angst, Fluff, to romance

Crush and oc had been a couple for quite a while now, and to say the very least, they recalled loved eachother. After all they had hit it off after final selection had happened. One day, crush was in the wistaria building as a group of demon slayers had been allowed to stay at the wistaria manor and rest up until a new mission would be assigned. And so, oc was sitting by themselves in the garden when their crow came to them, informing them of the new mission. Wanting to give crush a break from the events, they decided to go alone, making some form of excuse so Crush wouldn't follow them. Little did oc know, that the demon they were sent to ( Murker ) happened to be part of the 12 Kizuki ( I can't spell ), and it didn't take long for crush to catch onto what was going on.
