Oh so we are finally getting introduced to the second brother of Calypso, his name is Atlan, I think this was mentioned in the manhwa very early if I'm not mistaken 🤔 so a spoiler for him
Spoiler!
As you can see he is the hot headed brother out the three brothers and he also has memories from past life. He was actually trying to bully her in this timeline so she hates him or something (I don’t remember this part clearly because I read this spoiler on Internet months ago 😔) but it's later on it's confirmed that when Calypso tried to cut him off from her life bro cried like a baby to not leave him alone 😂
I like to post spoilers for the stories I find interesting because I don't have much time to read novel due to busy schedule
