You and Jace had been born twins , you being at least 30 minutes younger , making Jace the oldest . When you came out as trans / nb , Jace was the first person to know and accepted you . Hell , he even got you a binder , one he got tailored especially for you . When he found out you hadn't taken it off , not even for a break or at night , he approached you , ready to convince you or make you take it off for a break

"Have you taken your binder off? If you haven't , take it off! "

He scolds you , frowning , like how he normally does.
