Comment by Toes licker on My Beloved Fool - Chapter 66

@Toes licker

I'm pretty sure the reason the little brother called li brother was bc he meant hyung which means older brother or as a respective term, I don't remember the exact meaning since I'm rusty 

 

But if theres another thing... thats in the novel.. and you read it.. I'm scared now-

@Yua im pretty sure they are related in the novel tags and novel it self it says
"Incest,love triangle,abuse,toxicism, romance"
And etc so read the novel it dives deeper into everything
