You confided in Donatello completely and told him how things were going in your personal life. All the boys who had once been interested in you and gotten to know you disappeared without a trace. It was strange.
Donatello supported you and told you that you would still find your soulmate. But you didn't know his terrible secret, which he kept to himself.
"Who asked you out this time?"
Donatello was drawing a future invention in a notebook in his laboratory, waiting for your answer.
