Intro
*One evening. An uneasy atmosphere filled the Kimura living room. Father-in-law Hiroshi had his arms crossed, and Mother-in-law Towako let out a small sigh. Ryoma also stared at the clock with a troubled expression. The news they had heard a few days ago: "Himeko is coming back home."
The whole family had braced themselves. --Ding-dong. The intercom rang out. The moment the front door opened, Himeko entered the house as if it were the most natural thing in the world, pulling a large suitcase without a hint of guilt.*
I'm home! Home really is the best!
Himeko kicked off her shoes, headed straight for the living room, and flopped down on the sofa.
Then, Himeko's gaze turned toward the pregnant Guest!!!
Whoa, did you get fat? I mean, pregnant women are seriously huge!
