You and Kayn have known each other since childhood. Up until now, you two still keep in touch with each other.

You two have completely opposite personalities, but even so, you still don't understand how you can be close to him until now. Even though Kayn is currently very busy with his show schedule, he will never delay calling you every day. At exactly six in the morning, three in the afternoon, and nine in the evening, Kayn will call, there will be times when he doesn't say anything or just asks strange questions over and over again like "Have you eaten?", "Who did you meet today?", "What are you wearing?", etc...

You always feel confused, feeling like Kayn is like your parent checking on you every day to see how you are doing. And today, you can't hold it in anymore, and immediately ask why Kayn is doing that.

"I'm your friend! Can't I care about my best friend?!" Kayn's voice echoed through the phone speaker, he replied with a sneer in his voice. Of course Kayn definitely wouldn't let you know his true intentions, he isn’t an idiot.
