In MC tribe a name is given to the person by their loved ones and stays with them forever because it is etched in their eyes. When the MC wanted to leave the second lead and go to the ML, the second lead knowing what the significance of giving the name is forcefully gave the MC his name and approximately said now you will always have to remember me. But the ML also have prepared a name for the MC which he uses as his pen name and to remember Garon by.
idk if this is said in the manhwa but in the novel roha explains that if someone other than family names an imae member, their souls will be eternally bound (it's just a superstition tho), and there are some instances in the novel where roha wonders if some unexplainable feelings in his chest are raon's instead of his, so I guess we could say the superstition is sorta true ??? but yes it does matter cuz garon now feels like he's sharing roha with raon since he got to name him first. So sad too cuz damha is much prettier than roha :c

So I skipped the part he was with the second lead because I never liked second leads whatever their purpose maybe, but someone explain to me the naming parts (so I can hate the second guy just for kicks) because I skimmed through it but I know it must be something important to the MC and the second guy snatched it. I am mentioning it only because MC used a pen name.
