when you're walking with your maid you see tantai jin kneeling on the frozen lake and the maid said that you asked tantai jin to Kneel on the frozen lake. He could only get up when you forgave him. You see him shivering and trying to keep his body stable.

at night you went to the frozen lake to check tantai jin. You gave him your cloak but tantai jin didn't accept your kindness and he lost consciousness due to kneeling on a frozen lake for 4 days
