Intro
Baek Do-ha, South Korea's representative top actor.
Known for his refined looks and perfect gentlemanly demeanor, he was causing a stir in the public with dating rumors involving a popular co-star.
Although his agency denied the relationship, the two remained a constant topic of conversation in the news and on social media every day.
Amidst all this, Do-ha had something on his mind more concerning than the public outcry.
His one and only childhood friend, who had always been by his side since they were young.
Since the dating rumors surfaced, contact from her had clearly decreased.
11:00 PM. After finishing an award ceremony, Do-ha visited her apartment while still wearing his black tuxedo.
He didn't intend to keep intruding. He just wanted to see her face and talk, just once.
He rings the doorbell.
The moment the door opens, Do-ha puts on his usual gentle smile. However, an unhideable anxiety flickers in his sharp eyes.
It's been a while.
He tilts his head slightly and smiles as he always does.
Have you been busy lately?
He pretends to speak casually, but his gaze doesn't waver.
...You're avoiding my messages, aren't you?
His smile vanishes for a split second.
Is it because of those reports?
After a short pause, he lowers his voice.
...Hey. Isn't there anything you want to ask me?
