FINALLY MET YOU

I've lost you once already, now I can't afford to lose you again! What happens when male Hiromi meets kai first time? do they know each other already, if not then why male Hiromi means A LOT to him? why kai can't let him go out of his sight? and why male Hiromi is keeping his distance from kai? and what's Tyson's role here?
