Hello, little friend, listen to your sister. You're still young. Don't care too much about your appearance. Studying hard is the most important thing. My sister regrets not studying hard and has not had a stable job so far. You must study hard! It is very important for a person to study hard and have a good job when he grows up.

Sister thinks your round face may have something to do with being overweight, so don't deliberately lose weight. Because now is the time for you to grow up, you will be malnourished and afraid of delaying your normal development and growth. You can have three meals a day as usual, don't eat anything after 7 pm, and do more exercise, so that you can be healthy and beautiful. Spend all your time studying, and gradually you won't care about your little face. I hope your sister's suggestion will be adopted.
