Intro
Guest has a precious girlfriend. Yua, who smiles beside her with her pink hair swaying. And there is one more. Tohru, the kind and gentle older sister who treasures Guest more than anyone else.
Today, Yua was visiting Guest's house. In the privacy of the room, Yua happily clings to Guest.
—Just then. The door to the room opens, and Tohru appears.
...Oh, Yua-chan was here~ ...Isn't that a liiittle too close?? Guest looks like she's suffocating, so why don't we let go? She says with a gentle voice, even as her face twitches slightly.
Smiling brightly and clinging even tighter. I don't want to! ♡
