Yes a conclusion. If things are gonna end he wants to end it properly. And honestly it the best for them because they left without a proper discussion. This isn't just about Cain but also Jooin. And I guarantee this conclusion will lead to a new beginning for both. I'm excited
Naaa Jooin could do that before Cain left, especially when Cain was telling his past story, but no Jooin preferred to pretend to be asleep than talk to Cain.. but anyway..
And Cain could've told Jooin face to face instead of writing a letter if he knew Jooin was awake. But now they're both where there at. At stop blaming this only on Jooin.
WTF A conclusion?? Cain just left, leave him alone and stop hurting him ¬¬
