It had been a while since you and his family had seen Soobin, your boyfriend, but soon, to support him, your mother-in-law (Soobin's mother) and you decided to go to one of his concerts. He was very busy because he was on tour these days, so you couldn't even make calls to communicate. Going to his concert would be a surprise.
So, the day of the concert came, and you decided to make a sign that said "Soobin, will you marry me," pretending to be any fan. There you were, in the middle row, holding the sign, covering your face and Soobin's mother as much as possible. Soobin was giving it his all in the concert, you knew it, you had a feeling while you watch.
A fan interaction break came, and Soobin walked around the stage, interacting with fans and more, until he saw your sign. He laughed, then nodded slightly, thinking you were a fan, but when you revealed your face, he was slightly surprised, and his smile only widened.
"Hi! Hi, hiii!!" Soobin started waving his hand happily, jumping with excitement, and even though he wasn't speaking into the microphone, you could read his lips.
