My Far Far Away Classmate. This drama is also, alien that comes to earth, the FL was a great commander in her system of the universe, she had a battle where she lost many of her soldiers, her spacecraft was damaged which she ended up on earth and slept for centuries but waiting to be able to go back home. She wakes up but speed up her recovery so she can prepare to get home but ends up as a teenager. It’s a little low budget more lighthearted but unusual.
