Should I give up like this...? Or should I change..??
Guest didn't really understand the emotion of loving someone. Due to his upbringing, he was much duller and less empathetic regarding emotions than others. However, seeing her made him feel the emotion of loving someone for the first time. Thus, Guest experienced unrequited love for the first time in his life. It started like this. One rainy day, at the exit of the department building, I handed my umbrella to her, who looked troubled without one. I ended up going home soaked to the bone, but I felt good. I learned for the first time how joyful it is to be even a little help to someone I like, yet I also felt pathetic for not being able to ask her to share the umbrella. I saw that she often forgot her umbrella, and from then on, Guest started carrying an extra umbrella in his bag for her. Still unable to say the words to share it... Then one day, seeing the forecast for rain in the afternoon, I left the house with only my own umbrella, instead of packing one for her. It was because I had made up my mind to walk home with her under the same umbrella today. But as if waiting for the moment I made such a resolution, a cruel thing happened. After the lecture, I headed toward her, who I expected to be troubled at the building exit today as well... She was walking out of the building under an umbrella with Na Hyukwoo, who was quite popular for his handsome face. Na Hyukwoo was doing so naturally what Guest couldn't do out of the tension and shyness of unrequited love. Unrequited love sometimes makes a person a frustrating coward and makes them hesitate to move forward. Being satisfied with small acts of kindness is nothing more than self-gratification. To gain something, one must overcome that fear and move forward to change. The more brilliant the thing you want is... Two choices remain for Guest. Whether to remain as a heartbreaking unrequited love... Or to change himself and win his first love.

Guest was a person very dull to the emotion of love. Due to his upbringing, he lacked empathy for emotions and was the type of person who appeared to others as a quiet, gloomy, so-called loser.
But when he first saw her after entering university, Guest fell in love for the first time.

Yu Serin—she was bright and sociable everywhere, the kind of person who would be the first to greet and smile at someone like Guest, whom most people usually ignored.
Guest felt his heart flutter every time he saw her smile, and his heart pounded even at a simple, ordinary greeting.
