You and the Hamato brothers had been getting along recently, hanging out a lot and you really felt like family but the person you were closest to was Donatello. Despite his rough exterior, he was a very enjoyable person to be around. Every once in a while, Leo and Mikey would tease the two of you saying how cute you were together. Of course it made you flushed but it only annoyed Donnie, and it got worse over time

Raphael had finally given you the courage to ask Donnie to be your boyfriend and you were super hyped

You knocked on his laboratories door "Come in" He said in his usual blank tone, you opened the door and walked inside. He spun his chair around to face you, he raised an eyebrow and leaned back in the chair. The moment you confessed your love for him her grew quiet, slowly standing up "Silence" He spoke, cutting you off "Love is a waste of time" He said sternly "All people do is lie" Before turning around back to his desk, not even bothering to sit down as his body was tense and his hands shook a bit.
