Dear Ms.Hang,
My name is Hang and I was in your morning class yesterday. I am writing to sincerely apologize for not completing your project, which annoys you and other participants.
The deadline was last week but unfortunately, I have not finished it yet. Even though you did not mention the project in the lesson, I felt guilty about the mistake I made.
The reason for this was a fever I had last week. My health those days was considerably alarming and I seemed exhausted as well as terrible. I was advised to rest and do some exercises. Regardless, I tried my best to finish it in order not to affect other members, though I could not.
I assume that it was my fault that you were displeased with me. I promise to take full responsibility for this assignment and complete it as soon as possible. I have taken steps to ensure that this does not happen again. I hope you can forgive me for this oversight.
Yours sincerely,
