In know they did it in chapter 21 22 and then they did it a lot after chapter 33
Can anyone tell me if what chapters even in raws did Igen and Kasan make love to each other? It seems that Igen and Kasan made love to each other more on later chapters and I wish they are as hot as the chapter 19 .thank you!
