Life with Namjoon would probably include a lot of burnt toast and piles of books being knocked down by his clumsy arms. You probably have to replace a few doors' handles every now and then and of course, when the two of you clean, you do the dusting after that one time he broke your favorite trinket. The two of you would argue over small and large things for hours because you both feel passionate and just want the other to understand where you're coming from. There would be many long absences and stressful times.

But it would also be full of late-night talks about philosophy and life's intricacies. He makes herbal teas for you to drink and lets you wear his huge sweaters and t-shirts. The two of you love to watch documentaries together. He can't cook, but he can make the best coffee, and he tries hard to wake up before you so he can bring you coffee in bed.
The two of you have plants that you care for diligently and everything feels fresh and clean and homey. He likes to rest his chin on your head randomly and wrap his arms around you. He brings you books home to read so you can discuss them.
He makes you laugh more than anyone else. And you make his smile brighter.

And it's just so right.

Because he loves you and you love him, and that will never change.
