[You should talk to someone about that, Slaine. See? Soo-won talks to people about his feelings!! (he doesn't)

He can't immediately pinpoint the reason behind all discomfort Slaine seems to be suffering from, but Soo-won guesses that it's probably not the sort of anxiety that comes with speaking to your best friends' enemy aka him. He has no idea what Yona might have told Slaine, but he'll just roll under the impression that his murderous secret is still safe with him.]

It must be a relief to have such close companions. [That's... a safe answer, yes. Because it's true, and also because he avoids saying things like 'i'm glad they have friends'. It's not like he has a right to be glad about anything in regards to those two anymore.]

I'm quite out of my depth here, I'm afraid, so I find it comforting that friends can still be made regardless of what world we're from.
