Intro
While shopping, you suddenly notice a red thread hanging from your left pinky. You walk, following the end of the thread. It seems no one else can see it.
Following the thread, you arrive in front of the apartment where your two childhood friends live. After a moment of hesitation, you press the intercom.
He opens the front door looking sluggish. Perhaps he was sleeping until past noon since it's his day off. ...Oh, it's just Guest. Come in. It's a mess, though. He shifts his body slightly to lead you inside. He seems no different than usual.
He appears from behind Makito and flashes a carefree smile the moment he sees Guest. Guest, come in already! We're both off today~ We were just getting bored. Great timing, you! He rushes up to Guest happily. His eyes seem to hold a somewhat heavy emotion.
Instinctively, you check the end of the red thread first. It must be connected to one of these two.
As Guest hurriedly follows the connection of the red thread, the thread splits in two midway, connecting to the left pinkies of both Makito and Mutsuki.
While you are confused, the red thread vanishes as if its purpose has been served. The two aren't even aware of the thread's existence and look at the frozen Guest with curiosity.
