To sum it all up, he confused, he dont feel things but he dont want jooin to leave or he dont want to let go of jooin and he very confused why he dont want him to go, and this is a new feeling for him and he tells jooin (unknowingly) to atleast validate his feelings of not wanting him to go atleast.(i think, since jooin is the ONLY person he practically begged not to leave)
Ya'll, ive rooted for yawhi ever since, hes too honest atleast. CAIN IS SUS, AND I'VE HEARD OF THE SPOILER!
