Just wait until Alberu appears
You either shift to him or you decide to have them do a threesome. Cause I am with the last option
I actually ship him with Rosalyn, especially with the recent chapters of the novel of them working together whenever cale goes to his adventures. but im also not closing the possibility of a threesome because he is also head over heels for cale. i want to to see him already
Cale is can be ship with almost all the characters
He is universal shippable character
This might not be bl but i ship them both so bad cale/kim rok soo and choi han
