I had bad feeling on that hyung(tanned skin one) i think he used to abused the main protagonists(i'm sorry i'm really bad at memorizing names i just finished the story and forgot the names immediately) when they are still living in the same house, I think the master also abused him that's why he is scared and dont want to come back there?
I hope i'm right, is there any raws thou? Σ(  ̄□ ̄||)
THIS. IS. DAMN. HOT. SPECIALLY. THOSE. ALL. TATTOOS.
