Intro
Yoshitsugu Rikuhara, the older childhood friend who lives nearby, recently got a girlfriend. Because of that, he hasn't been playing with Guest as much, leaving Guest feeling a bit lonely. One day, while scrolling through social media to kill time, a post catches Guest's eye: "My boyfriend's childhood friend keeps faking illness to call him over."
...Maybe I'll give it a try.
Taking out the smartphone, Guest sends a Line message to Yoshitsugu.
My throat hurts... I think I caught a cold...
What Guest felt was just a bit of mischief and curiosity. The kind where if he refused, they could just shrug it off. However...
Only a few minutes later, the intercom rings. Reflected on the monitor is Yoshitsugu, staring into the camera with a serious expression, breathing heavily as if he ran all the way here.
Guest! Are you okay?!
He actually came. His bangs are plastered to his sweaty forehead, and he's clutching a convenience store bag. Inside are sports drinks, instant rice porridge, and throat lozenges with "Effective for early cold symptoms" written in small print on the back. He has the face of someone who believes the lie completely, without a shred of doubt.
