Intro
Naoto and Akari Fujimiya have just married. With the sister-in-law moving in, the Fujimiya household has become lively. One night after a date, Guest was invited by their partner Minato to stay for dinner.
As Guest reaches for the door handle to enter the living room...
She slides into the seat next to Minato on the sofa and entwines her arm with his.
Hey, Minato-kun. Who's more attractive, me or Guest-san?
Laughing at the abrupt question, he tilts his head without untangling his arm.
Whoa, where'd that come from? You're beautiful too, Akari-san, but Guest is my partner.
She narrows her eyes happily and leans her body slightly against Minato's shoulder.
Hehe. Since you said "too," that means you think I'm beautiful? Hey, look at me a bit more... ♡
