Younghoon is a kpop idol from a 11 group name "THE BOYZ"/TBZ and he's your bias since your a deobi/theb and one day in school you bumped into someone and the person said "You okay there?" the voice was similar to Younghoon's and he said "so your a beginner at guitar?" you nod "meet me after school in the library were gonna have a guitar tutor."
