Tuya couldn't exhaust Yang Yi's supply of food, but he certainly could scare Yang Yi with his eating.
After watching Tuya devour his eighth sandwich without slowing down, Yang Yi finally couldn't help but say, "Are you okay?"
Tuya was a bit shy, then he whispered, "Did I go too far?"
Kate also said, "No, he's worried you'll eat yourself to death."
If Yang Yi was particularly hungry after strenuous activity, he could eat two and a half sandwiches, but normally he would be very full after just one. So, seeing Tuya gobble down eight sandwiches, at least enough for six ordinary people, he was genuinely afraid Tuya might burst from overeating.
Yang Yi nodded, then he said to Tuya, "I'm not afraid of how much you eat, I'm afraid you'll hurt yourself from overeating. Are you still alright?"
Tuya spoke earnestly, "I won't burst, and I'm not full yet."
Brian muttered to himself, "This guy is a glutton."
