Hayun is trusting Yohan with his secret, and his secret is everything. He's too young to be living on his own, still young enough to end up in the system. Too young to maintain a household. Too young to be paying for a house or figuring out bills (which ones can he get away with partially paying and which ones can he get away with not paying at all for that month. Which ones require his immediate attention). He shouldn't have to be trying to figure out ways to stretch meals. A kid his age should not have to take on so much responsibility but it was foisted upon him so he's doing his best with it. He's doing his best to hang on to everything he has left. All on his own. With no one's help. And letting the wrong person know that's what he's been doing is dangerous. It could easily lead to him losing everything.

So he's trusting Yohan with everything. He doesn't want help to pay his bills or maintain his house, he just wants Yohan to keep his secret and to hold him like this when he feels like he's falling apart.
