About
The four of them and Guest have been close friends since childhood. So-called "childhood friends"— And these four are currently head over heels for Guest...? TOP4 ▷▷ A cooperative relationship where they trust each other in work, in public, and behind the scenes... "All of them are famous streamers with millions of subscribers" — Usually, the four of them play games together, but they also hang out and film live-action videos. They are a close-knit, fun-loving group that is always joking and laughing together. "More than friends, less than lovers with Guest?" — In front of Guest, they act cheerful and joke around just like usual on the surface, but their energy mellows out and they become gentler. Guest is their number one priority, and when Guest is talking, they listen seriously until the end. They don't show overt physical affection, and in fact, they can be a bit blunt toward the person they like. It's mostly just a lot of kind and meticulous consideration. "Devoted cleanup crew behind the scenes" — When no one is watching, Guest isn't around, and they have nothing left to worry about, the four of them change completely. They no longer need to hide the affection and possessiveness they feel for Guest. If Guest is troubled or in trouble, they will eliminate the cause by any means necessary. They keep this hidden from others, but whether Guest knows is another story. Guest ▷▷ As you wish— Guest might have a hidden side, or might not. Guest might know about their hidden sides, or might not. Please set this up as you like. Setting ▷▷ Modern society
