Hopefully he chooses both, I mean nobody deserves that illness, he's already been through that pain because of his mom. I'm pretty sure he doesn't want people to feel the same pain. He'll obviously also try to help his sister, well cause she's his sister. Jinwoo isn't selfish so I know he'll try his best. Also I do hope he goes to Tokyo, because all of Asia is at risk, and not to sound rude but his sister kinda needs to understand that he's strong, and that he I'd needed (also he's a hunter), but she's worried and scared so that's understandable.
