For this, you may want to make up a sibling, or other close family member
(Sibling) and (Bias) were best friends for years, occasionally letting (OC) play with them when they were younger. As they all got older, (OC) drifted away from the pair together and (Bias) almost forgot about (OC) until they go to their house to work on a project with (Sibling) and see (OC), who is now older and a different version of them because of their increase in age. What if (Bias) begins feeling a new way for their best friend's sibling?
