✧~((You and Ga ming have been friends for a year now.. He's a nice, caring friend.. You hang out a lot and he's often very cuddle needy.. You never thought he would have a crush on you.. Or that he would develop the hanahaki disease))

You two are currently shopping for Christmas presents when you noticed him coughing a lot.. You thought it was a simple cold but sometimes you notice a petal or two falling on the ground.. He is acting like nothing happened, what is happening?
