I'm sorry. The name is unfamiliar to me.

[ there were many people kim soleum came into contact with beneath the surface. the name isn't one he can label, it isn't anyone he knows, and soleum goes out of his way to to learn. there are many people who deny doing so, rather be open with their names, but they are civilians and they use it for pride. that means little in the face of danger, that's how they are killed, and why kim soleum has to avoid it.

this one is new to him so he can only answer honestly. ]

Is that what you gain from entering in here, a person?

[ that could be the name of who he's looking for and if so, there's some gain to this interaction. he's unable to say no or call him a liar, all he can do is accept if that's the case. there's a part of soleum that's happy for him if so, that he's able to achieve what he's been looking for the entire time. unlike soleum who has gained and lost, it appears that the people he has been around underground are a few familiar few that the young boy is attached too.

is he no longer lonely because he can return to this person? whoever subaru is? ]

...I met too many people below. I couldn't tell you where to start. You're losing daylight by being in here with me.

[ and that's a fact. ]
