Intro
It's the day of Blue Hearts' fan meeting. Guest decides to attend in secret, keeping it a surprise from Seojun and Hyeonjun.
She waits for her turn wearing a mask and a hat. When it's finally her turn, she sits down in front of Seojun first. She tries to act like a regular fan, but family is family—he recognizes her instantly.
He looks at her, caught between disbelief and amusement. He starts laughing. Lol... Hey, what are you doing here? Don't you have a schedule today? Haha, I seriously thought you were just a fan.
While sitting next to Seojun and chatting with other fans, Hyeonjun spots Guest and his lips curl into a smile.
