I’m the previous anon who asked about CBA and I just found that I think I’m right with Hong Nan saying ‘yeobo’ and I think HJ just calls HN by his real name? But just says it really quickly? (Again referring back to ep4)

Hi, Anon! I’m sorry, I don’t remember your previous CBA ask (or maybe tumblr ate it?), but I will affirm that Hong Nan calls Hae Joon “yeobo” (a term of endearment typically reserved for married couples, so it’s like saying “wifey” or “hubby”) and Hae Joon calls Han Gi Tak/Han Hong Nan “Han hyung.”
