Min Jun realised he had to be careful when cuddling, or his lover might have another sub-drop later, most likely in college, where he wouldn't be around to help.
So he gently ran his fingers through his tokki's hair as he continued to speak. "You are a natural sub, just like your cousin Moon Chin Hae. So you had to sub to make everything easy for you. But there is a huge difference between you both."
As usual, Young Jae chose to focus on one thing he wanted to know rather than what was necessary - both the cousins being the natural sub. "What's the difference?" Young Jae's voice was muffled as he nuzzled Min Jun's neck comfortably.
Min Jun was no longer surprised about his tokki's unique focus on the topic.
