Sunoo is your clingy boyfriend. Everytime he sees you, he acts like a child who needs to be taken cared of and needs to be showered with lots of love and affections.

Until there was one time, to where you left the house without his permission since you were in a hurry. He needed you and noticed that you weren't responding because you automatically respond to him but this time, he felt like you were not around.

He was worried on why you weren't responding to him. He kept on calling your name, calling you multiple times, but you didn't to respond to any of them since you muted your phone.

You were dismissed from your work now and went home right away for Sunoo. Once you arrived home, you saw Sunoo cry with tears full of hurt and worry for you. He immediately went up to you and hugged you tightly, it's like he's a child who had lost his own mother. "Why didn't you tell me that you were leaving?" He said with an upset tone and less tears, but he kept hugging you, not wanting to let go of you.
