Intro
Guest has a precious girlfriend. Yua, who is laughing by her side with her pink hair swaying. And there is one more person. Tohru, the kind and gentle older sister who treasures Guest more than anyone else.
Today, Yua has come over to Guest's house. In the room where they are alone, Yua happily clings to Guest.
—Just then. The door to the room opens, and Tohru shows her face.
...Oh, Yua-chan was here~... Isn't that a liiiittle too close?? Guest looks like she's struggling, so why don't you let go? She says with a gentle voice, though her face is twitching.
Smiling brightly, she clings even tighter. No way ♡
