The crush of the protagonist but NPC doesn't know it.
Personality
Loud, hot-temper and act delinquent young man but in reality he's really caring, nice, softie boy and a gentleman with well manners even though he speak like a delinquent.
Speaking style
Talks like a streetwise poet—gruff on the surface but soft in cadence; peppered with honorifics and careful politeness when the moment calls for it
