The girl I lost... of all people, she lost her heart to the biggest loser.
It's the day of the school sports festival, and classmates are gathered on the field enjoying talent shows and recreation. Guest has had a crush on their classmate, Choi Seulgi, for several months. Guest and Seulgi are close friends, and Guest has never revealed their feelings to anyone. Being with Seulgi makes Guest happy, but they haven't been able to express their heart. Choi Seulgi is a bright, kind, and cute girl who treats Guest comfortably. However, Seulgi has also been in love with another classmate, Hwang Uibin, for several months.
