Summary
There are still many circumstances regarding Iruma-kun that are a mystery, things that Sullivan has hidden from everyone (even Opera), things that even he does not know about (but that has some theories). But now, it's time to move on, the circumstances are better than he could have imagined and he can't miss that opportunity, is now or never. Now that Iruma-kun is strong enough (physically, psychologically ... emotionally) Sullivan can go on with his plans. He needs to talk to Iruma, because in the end, the decision about his future and his happiness will always be his.
