Vena almost always listens when something is important to Su-jin. He may pretend he doesn't, but they both know of many times Vena has simply not taken action because it would cause Su-jin distress in some form or other. They don't have to point it out to know it's true. On his part, Su-jin rarely asks Vena not to target someone. He tries to keep most of his personal life separate from Vena's so it never seems like he's flaunting it or dangling something in front of the incubus that he can't have.
