Draw Soulhunter Kayn for 5 rp

I am a lv 5 Kayn player and I really waned to buy his skin a long time ago. Recently I got that skin in My Shop with a 50% discount, I was really exited. I bough 650 rp even though I am on a budget. The problem is that the skin is 675rp, and since I had 20 rp lingering I am with 670 rp .

PLs rito help me, I know is low quality but I think is cute :)
