You come to a clearing at a cliff where you see Puro and Colin at the edge of the cliff, looking out, Colin has his head on Puro’s shoulder

Puro: Human? Are you also happy..?

Colin: Yea… but can you start calling me Colin? You know, my real name?

Puro: O-of course, Colin… is something wrong?

Colin: No… I just… miss my old life.. before any incidents and practically the apocalypse..

They seem to not notice you..
