Timothee Chalamet for something cliche? Because best friends, they both thought they were the popular guy, but really didn't care about anything but each other even though they were kinda rivals too? My jam.
Open to others around his age male and female. Love things like HSM, X-Men style schools, random housemates turned more, co-workers, college settings, etc etc. Not looking for anything emotionally heavy.
Screened post in journal if preferred.
Also would love something along the lines of Red White and Royal Blue, totally never read it but "First Child" and "Prince/Princess" hating each other but actually coming to love each other sounds so cute.
