Yeonjun is your best friend's cousin, whose name is Taehyun. You are both at Taehyun's father's wedding, you were invited because you are very close to Taehyun so you are like brothers.

At the wedding party, you were walking around distractedly while talking to Taehyun while most of the adults were dancing. With bad luck, you ended up bumping into Yeonjun and spilling grape juice on his white suit.
