The care is in the details (3/?):
Mhok gets into a fight with Porjai's a**hole of a boyfriend and, in the heat of the fight, he forgets about Day.
A carbon copy of the situation that got him into prison a year before.(and that P'Aof so *graciously* reminds us by filming and editing both scenes as mirrors T_T)
And when he loses his temper, he loses his sense of duty too.
(There's a theory going around that ponders what if, in the first episode, the call he receives and dismisses without answering before the fight is either from his sister or Porjai - to tell him about his sister's death:
Something that probably is haunting him ever since.)
So, in the fight scene in the market, when the shop owner comes to see the disaster they both have created, he says the magic words:
'Who will take responsibility?'
And that's when Mhok snaps out of it and remembers Day.
He panics and becomes desperate because he has made the mistake of letting his temper get over his common sense again and that could mean he could lose another person he cares about.
His reaction when he eventually finds Day says everything:
Teary-eyed, anguished and relieved at the same time (the way he breathes out speaks volumes). He didn't lose Day like he lost his sister, he finally found Day safe and sound.
I'm sorry, I really am. You're ok now. I'm right here, okay?
And he cares so much that he will make sure he's not letting him go ever again.
