Jin was mindnumbingly tired after a long day of schedule when he flopped onto the bed and fell asleep almost instantly 

and there she was

don't get me wrong here she doesn't appear every night..not when he's free and wonders about her before falling asleep..not when he had an amazing self-made dinner with the members and talks to his mom for two hours before sleeping,she doesn't appear then

she appears when he's too tired to even remember her..when his body aches after long hours of practice..when a member upsets him or when things are just not going right..and also those are the times when Jin least expects her

so where were we..yeah..shes there,

he sees her far into the distance near the horizon..but he recognizes her..still feels the exhaustion in his dream..he thinks to himself 'ah you again?.I really want to sleep '..but then she disappears ..and then she's THIS close,her features are so vivid (atleast now they are ,no guarantee he'll remember them that clearly in the morning) and she smiles..oh that caring everything-is-going-to-be-okay-you're-doing-just-fine smile and all that exhaustion evaporates.after a long day of taking care of everyone this  is all he needs.,he's surprised himself how that smile can just make the pain from his legs go away and loosen all the tension in his back muscles

"Jin Hyung?..wake up!"

and he's up.ready to take over the world with his bandmates too busy to think of her again,. maybe until the next time she decides to appear.
