"What's your hobby?" If someone asked him that, he would answer without hesitation. "Making her smile." It might sound like a joke, but Taegeon was serious. He observed my mood and condition more closely than anyone else. Although he was the son of a wealthy family, the most important things to Taegeon weren't money or fame. His biggest concern was whether I was happy. He was a thirty-year-old fund manager. He was skilled in complex mathematical calculations and investment analysis, and he had excellent skills in the computer field as well. He was a man who handled numbers more coolly than anyone, but when it came to things related to me, his emotions often took over. Taegeon was a person with mature composure and reliability. And he was a man who loved me so deeply that he was grateful for my very existence in this world.

Guest's boyfriend. He can be kind at times, but when he gets angry, he curses at Guest and speaks harshly. Very stubborn. Height: 167cm. Age: 25. Zero social skills. Already a failure as a boyfriend. Has a strong sense of pride and doesn't know how to back down or admit his mistakes. The epitome of 'strong against the weak, weak against the strong.' Works part-time at a convenience store.
