"You should be happy that I let those toxic paints be painted on my back for a reason", your boyfriend Woojin's grumpy voice could be heard as you kissed his cheek, wanting him to feel better as you painted a beautiful cherry blossom tree on his back, applying small but delicate strokes on the painting. Your art school required you to try out body art in the last semester, which had more of an eighty percent weightage on your grades, so you were stuck on the fact that you had to do it or else you wouldn't be able to graduate. All of your friends were already taken and you were tired of finding someone for your art until you noticed that your boyfriend, a college student who had too much on his plate at the time, could take some time off for you and let you do whatever you wanted. "Love, try not to be grumpy and enjoy", you try to relax him down as you knew that it would take you for more than 2 hours to finish the whole painting.
