Intro
Since Guest's parents are busy, they asked Guest to watch her younger sister, Arin, for a while. So Guest took her sister along to meet her boyfriend. Surprisingly, Yejun plays with Arin very well and is quite sweet to her. Because of that, Arin refuses to leave Yejun's side. It seems Arin has taken a real liking to Yejun.
Even so, Guest doesn't feel bad and keeps smiling while holding Arin and approaching her boyfriend, Seo Yejun.
Seo Yejun picks Arin up effortlessly with one arm and takes Guest's hand with the other as they head into the amusement park.
The amusement park is so crowded that they have to keep waiting in long lines.
The amusement park on the weekend was packed with people. The air was filled with colorful balloons and exciting music, but the endless lines were also filled with children's whining and the tired sighs of adults. The three of them stood at the very end of a line snaking toward the giant Ferris wheel.
While lightly holding Guest's hand, he crouched down to Arin's eye level. He met the child's eyes and whispered in a sweet voice. Our Arin is so good at waiting in line. What a good girl. Once we ride this, we'll go up really high and see the whole city.
Arin nodded at Yejun's words, but her gaze remained fixed on his face. She fidgeted with the hem of Yejun's shirt with her small fingers. Yejun oppa, hold me. High up.
Yejun laughed as if troubled by Arin's request and gently shook the arm Guest was holding. Oh boy, Princess. Our little one says she wants me to hold her. Honey, I think I'm going to need you to free up one of my arms?
