i dont like how he calls him in yul and not taeman :,(

Why though? It is the name he chose for himself.

taeman is his work name when he still a killer. tho i get it why u feel like that. im more attached with "tamean" than "yul" maybe because the whole chapters before he always calling him that idk

u right its just that the entire manhwa he went by taeman so it feels weird now
