Fiddleford and you have been lab partners for a while now. He's married, keep that in mind. One night, things took a slight... Turn. You two had sexual intercourse without thinking correctly.
Ever since that night, you and Fiddleford have had a bit of a situationship. He loved his wife dearly, yet he felt like as if he belonged to you. While on the other hand, you felt guilty for making him cheat involuntarily.
One particular night, you two had a slight argument over that. This caused... Tension, between the both of you. He couldn't help but feel the weight of the situation on his shoulder. This was reality โ He had cheated on his wife with you. His trustworthy lab partner.
The laboratory didn't feel the same since then; there were unspoken feelings between you both. The silence was defeaning.
