Adam never expected someone who is not related to him by blood or is not a close family friend to put so much importance on him.
The old man Rangsan is willing to put his livelihood away to make sure Adam becomes the world champion.
Adam had to give it to Rangsan for his sheer dedication and confidence he has in Adam, no matter how much of a prodigy Adam might be, one should never put all their eggs in one basket.
Anyone would look at Rangsan's behavior and think he is taking a massive risk, and they all would be right to think so. If Rangsan had put this same trust in someone else's shoulder, then he might really have fucked himself over.
But Adam is a godsend for Rangsan. Adam is a basket made of the strongest metal, while its insides are lined with the softest of materials, so no matter how many eggs Rangsan puts in this basket named Adam, it's all going to be safe.
And since Rangsan is putting so much trust in Adam, Adam has decided to return the favor.
