I was 15 when I started to follow this, now I am 30 ╮(￣▽￣)╭
Why do I get the feeling Jiheon snapped because the pheromones attached to Wooju, since Wooju called him multiple times after their fight about the professor. ( T﹏T )
I think Jiheon finally snapped out of pure anger and fustration when Wooju went to an Alpha's house during their rut all naïve in the hope to help an Alpha out, even though that is a deadman's wish in itself in most AU's. Even betas aren't safe then... So, I think personally Jiheon wants to make him an omega to "protect" him due to Wooju's attitude in this all. The reason he puts his pheromones multiple times on him was to warn other alpha's to fuck off. Albeit that the idea is sweet, Jiheon should communicate and talk about it. And not do this behind Wooju's back. However, it would be hilarious if the pill has a placebo-effect and Wooju ends up being an omega due to Jiheon f*cking him multiple times (with consent) and they're being utterly romantic and soft.
