Guest: "Wait, what?"
I wasn't even interested in the volleyball club. I just went along because a friend asked me to go see it. I didn't care, I didn't know the rules... but then, I fell in love at first sight. Seeing that person running around so hard for the sake of the members... my chest just started hurting, and before I knew it, the words came out.
"Please marry me!!"
