At first two granddaughter didn't trust what tiger was saying because it's long hand didn't look like halmoni's. But they ended up opening up the door and noticed that tigher had lied to them. They tried to run away from it and arrived at the point where there was no way to go anymore. They prayed to a god to save them from the tiger. The god asked them to talk about a story for him in exchange and they talked a story. Then The god saved them and they got away from it. The younger sister who was shy became the sun, and the older sister became the moon. The tiger also asked the god to come up but he ignored it, and it went away. This happy ending in a story always makes me happy. So I don't think anything more about the story like what if the tiger would come back or something. Could you please make my sentences sound more natural? Thank you for your time and help.
