The book signing event had been over for two days. Woon appeared to be rushing around the kitchen, preparing something. While working, he is humming a pleasant melody. He is attempting to bake a special cake for his beloved's birthday. To complete his appearance in the kitchen, the man wore a blue apron. No one would have imagined from his current appearance that the man was King Hwon Woon of the greatest kingdom on his planet.
   Today is his lover Eun Dan Oh's birthday. This is Woon's first opportunity to spend time with Dan Oh on her special day when they are living together in this manner. Woon wants to do everything he can to make her happy on her birthday. Woon purposefully designed a personalized birthday cake for his girlfriend. 
   Although Woon is the ruler of his planet, the experience of living alone on Earth for the past year has inspired him to begin honing his culinary skills in order to save money. Although it was his first time making a birthday cake, it did not damper Woon's spirits. He glanced at the time; Dan Oh had to be home shortly. He pulls out his phone and dials her number.
    "Where are you?" he asks as their phone connection connects.
   "I'm on my way home, but I might need a little more time, sorry. People at my office insist on celebrating my birthday and congratulating me on the success of the book signing event, even though I just want to enjoy it with you," his girlfriend says.
    "Don't worry, they do all of that because they love you." We still have a few hours before the day ends; it's still 9 p.m. I'll be waiting."
   Woon prepares the table and the cake for Dan Oh's birthday after they finish the phone call. He looks around to ensure that everything is in order. He then decides to take a bath in order to greet Dan Oh with a clean and pleasant scent.
   "ting tong ting tong" Woon heard the apartment bell ring. He immediately dried his hair and applied perfume to his body.
  He remembered Dan Oh saying she was already on her way home. Woon's brilliant smile suddenly came on his face as he realized the person who rang the bell might the one he was looking for. He instantly walked to the entrance and opened the apartment door for his beloved.
   But, contrary to his expectations, the person standing at the apartment door was not the petite woman he was looking for. He even spotted an attractive tall man carrying a large bouquet of flowers in his hand while smiling broadly. The man is Dan Oh's ex-lover, Baek Kyung. Woon and Kyung's smiles fade when they notice another man at the woman's apartment named Eun Dan Oh.
    Kyung squinted his eyes as he checked the apartment number. He is certain that this is Dan Oh's apartment, but why does a man appear from within rather than his best friend? He fixes his gaze on Woon's face, who appears to be familiar.
   "Can you tell me who you are? Isn't this Dan Oh's place?" Kyung inquires cautiously.
    "Hwon Woon, Dan Oh's boyfriend," Woon replied firmly.
    "Ah, is that Mirac's man or something?" Woon, he remembers that name now. He recalls Dan Oh sobbing in the park in front of a massive tree while calling out his name, and how miserable his life has been since Dan Oh insisted on finding a way to meet him again.
  Kyung's heart had shattered three years ago when Dan Oh told him that she had finally met Woon and decided to be in a relationship with Woon. He's been waiting for her for eleven years so she can love him again. But, unfortunately, the man from another reality he doesn't recognize emerged and dashed his hopes. And now the man who took away the lady he loves is right in front of him.
   Kyung decided to focus on his athlete career after Dan Oh told him about Woon three years ago to wash away any leftover feelings he had for Dan Oh and to keep his mind busy from the notion of her. So, when he learned about his training in America, he jumped at the chance, hoping to forget his first love. But it doesn't appear to be as simple as he expected.
    "Why are you here?" Ask Woon to Kyung coldly. There is tension between the two men who stand tall and face each other.
  "I'm assuming you recognize me because you don't ask who I am. Why? Is it illegal for me to be here? Dan Oh is a special person to me, and I'd like to celebrate her birthday with her; where is she?" Kyung is unmoving, while Woon appears to be scary.
   "She hasn't arrived yet."
    "What are you doing in her apartment when she isn't even there?" Kyung is very inquisitive. Woon refuses to answer the question. He could simply tell Kyung that he lives with Dan Oh, but telling him that he is living in his girlfriend's apartment because he is homeless is rather embarrassing.
  "Do you live together with her?" The athlete continues since he does not receive a clear response.
   "I believe that is none of your concern."
   "How heinous. Aren't you a king or some other important person on your planet? But how did you end up as a useless man who even follows his lover and lives in her apartment? Do you lack self-esteem?" Kyung made a caustic remark that stung Woon's pride.
    Woon snatches his collar in wrath. He is already embarrassed by his current circumstances. Even Kyung never brings it up. He never wants to be a burden to Dan Oh, but being on Earth makes it difficult for him to obtain the steady existence he desires and with which he can be proud. So Kyung's words irritated him considerably.
    "What exactly are the two of you doing here?" A woman's voice emerges and draws the attention of the two tall men. Dan Oh had just stepped out of the lift and is walking towards her apartment when she notices Woon grasping Kyung's collar. The two men look to be preparing to punch each other.
