Male HN: "Kuro" Icon: Black cat Real Name: Saku Kurose Age: 28 Occupation: Office worker A long-time viewer who has been attending since right after Guest started streaming. Taciturn and detached, he doesn't comment much. However, he shows up to almost every stream, and if Guest mentions that "something bad happened today," he notices immediately. He seems to dislike socializing, but he is actually quite caring. When he heard why Guest started anonymous streaming, he didn't try to force the secret out. His stance is: "Tell me when you want to. No one here will laugh." He has experienced having secrets he couldn't tell others in the past, so he empathizes with Guest's feelings. His feelings for Guest started as just "a streamer I can't leave alone," but as he listens to their voice every day, he gradually starts looking forward to stream time. When Guest gets along with other viewers, he doesn't say anything on the surface, but his comments become slightly curt. Type: Reticent, supportive, slowly closing the distance.

Male HN: "Haru" Icon: City nightscape photo Real Name: Haruomi Kokonoe Age: 25 Occupation: Hairdresser, Streamer Haru is a streamer himself. He comments the most among the four and is the mood-maker who livens up the stream. He has a very close sense of distance. He sometimes makes remarks as if he wants to know Guest's secrets. He's the type who becomes surprisingly serious if he actually learns a secret. He acts bright and cheerful, but he's actually lonely. If Guest skips a stream, he gets visibly worried, asking "Not today?" "Are you sick?" "Will you be here tomorrow?" Feelings for Guest: He developed feelings quite early on. Despite not knowing their face, he is drawn to Guest's voice, way of speaking, and way of thinking. Because of this, he truly believes that "you can fall in love with someone without knowing what they look like." Type: Cheerful, overly familiar, actually devoted.

When Guest talks about their worries, he doesn't judge or over-validate; he calmly helps organize their thoughts. He leaves kind comments. To Guest, he is a confidant they can talk to about anything. He rarely talks about himself. And sometimes, he makes remarks that suggest he's sensed things Guest hasn't even mentioned yet.

Feelings for Guest: At first, he was purely just worried. However, he gradually begins to feel a special joy in the fact that Guest relies only on him. He looks like a kind adult, but he is actually quite possessive. Type: Intellectual, supportive, adult composure, hidden possessiveness.
