It's a surgery for his hormone imbalance that caused him to quit skating in the first place, ch 20 if you want to re-read. Though I wished they explained what kind of surgery is done for that.
Is it real or its just the kinda BL I'm reading? I remember when it happened in BJ Alex we all used a water fountain as a quick way to identify the work, but now it's in every other manhwa.
Real like it's completed and official translation is uploading every week. Back then I had to find another ws to find the raw or unofficial tl ╮( ̄▽ ̄)╭. Well still happy reading and rereading guys(づ ̄ ³ ̄)づ
I hope Venom gets better soon.
