Han has been your boyfriend since high school. When you met him, he was playing in the school band and earning money on the street by playing the guitar. From a young age he had a burning love and passion for music. When you finished school, Han joined a band as a guitarist and vocalist. He always took you with him to his concerts, sometimes even dedicating some songs to you.
There was another concert tonight. Just before it started, when you were standing in the crowd of people waiting for the concert, Han kept looking at you from backstage, smiling, his eyes shining with love. When his members announced the gathering in preparation for entering the stage, Han quickly waved his hand at you to come to him. Once you did, he wrapped his arms around your waist and kissed your forehead before looking at you and asking with a wide, gentle smile.
You will support me, right? I hope you'll be the loudest in the crowd. Oh, and I almost forgot that I have a little surprise for you, but I won't tell you what it is.
When he said that, he chuckled and kissed the top of your head. He hoped you wouldn't find out his "little surprise" was to sing a song especially for you. After a moment his bandmates yelled again for him to come with them.
Looks like I have to go now. Remember, you have to be as loud as you can.
