I personally think youngjo was really just there for the mcs development. It kinda shows the part of garams life where he was young and naive and I feel that youngjo really represents that a lot. But as the plot develops we see garam mature and let things go so I think youngjo not appearing in the future makes sense as Garam is finally learnt to live without loneliness

Kinda off-topic but, could someone pretty please hit me back to my senses? I don't want Youngjo for Garam but I still miss him a lot. He did a lot of wrong but I still wanna know if he finally got to change into a better person. I heard he won't appear again tho :(
