Kuru: Remember, to mark what is yours
Haru: Yes mama
Also Haru: Literally marks papa (face) with her name on it
Kuru-mama: (NOT LIKE THAT, DEFINITELY NOT PAPA)
Also Kuru-mama, maybe: (If that's how it is, then his unique part down there is exclusively mine, and only mine)
That night, papa might get night-raided by Kuru-mama, most likely
I could totally see Kuru deciding on a whim to pin him down and scribble her name all over him after this.
(or at least maybe scribbling on his inner thigh and abdomen like those old hentai tropes. )
