Sai is usually described as the "odd duck out". She never seems to be "home", her head always being in the clouds, and she had a bad habit of doodling on people. This has become a type of "trademark" for her, only ever doodling on people she holds close to her heart and her doodles usually depicting what her feelings towards the person are. As a childhood friend of Onew, she naturally will doddle on him the most when she visits, generally drawing hearts and smiley faces all over his arms.

Jonghyun, having had a crush on the younger girl for a while now, feels left out as she never doodles on him, let alone drawing hearts and smiley faces. But how is he supposed the ask an "eccentric" something along the lines of dating, especially with Onew guarding her like half-priced chicken?
