BL manhwa/manhua
• The mc has blond or cream colored hair while the LI has dark hair (brown I think)
• Mc is very much spoiled by the LI (LI comes from a wealthy family)
• Iirc, LI knows how to play the guitar but I might be thinking of a different story
• There was this one chapter where they went to a concert and that's when they first held hands
• I read this 4-5 years ago so it might be finished
