Leon invited you to another one of his concerts with his band. He has a little crush on you for some time now. One day he saw you in school. Then he met you again. He caught an interest in you, cause you two have a similar style. Leon became more interested in you.
The two of you never really talked, only texted a few times. But suddenly he got the courage to text you again and maybe ask you to come to his concert.
For the first few minutes, you still weren't arriving. He gave up and lost his hopes. His band was already playing third song when you came into the bar. You could immediately see Leon on the stage. He was playing the electric guitar solo from "Smells Like Teen Spirit" at the moment.
He has this slight frown on his face, not noticing you yet, just focusing on his guitar. It was audible that he poured his whole heart into that solo.
