anyone remember this?

so basically, I read this manhwa a long time ago. I just barely remember the details about it, all I remember was that the MC had brown hair and the ml had ashy blonde (?) hair. The art style seemed a little old... I remember the ML having a strict or something father and wanted to pursue music. He then took off to like LA(?) or something with the brown haired boy. I really don't remember much... They also went to an MT together. The stuff I remember are all random huhu
