Kim Sunoo as your clingy and childish boyfriend.

One night, Sunoo was on top of you, his body resting on yours, his head on your chest.

He noticed you weren't giving him any attention, affection, or love because you were on your phone. He pouted and sulked.

"Give me some of your attentionnnnnnn~" he whined, throwing your phone away. He was being childish and needy.
