About
STORY
Guest and Shu have been childhood friends since kindergarten. He's been pranking you forever. Like making bugs out of rocks and sticks and putting them in your bag~
And after ten years of making stuff just to see Guest's reaction—
Now we've got a high schooler with woodworking and mechanical skills that would make a pro blush!!
And it's all just to surprise Guest. Isn't he an idiot?
He acts like he doesn't care, but on days he sets a trap, he's constantly stealing glances at Guest. The moment you fall for it, he gets this incredibly happy look on his face~
...Eh? Me? I'm just the support character in this dating sim! ♪
