LOL—leaving Yuzu with tfw you sleep with your soulmate every night but can’t even masturbate for fear of waking them up.
Did that actually come up in the manga? I had a fic idea along those lines, though more like Yuzu going "fuck it, I'm going ahead anyway".
No, I’m pretty sure it hasn’t, nor anything like it. Maybe they’ve spooned? Almost, or on a special occasion, maybe? They’ve displayed a level of denial of the flesh worthy of a pair of medieval hermits.
I don't think masturbation exists in citrus. Like, even people thinking about it. It was never invented.
Or maybe it’s one of those timeline-erasure things, where the villain somehow alters elements of the reality, leaving the people with the sense that something’s missing, but they can’t quite remember what it was:
Yuzu: “Wasn’t there something physical we wanted to do?”
Mei: “You mean like kissing? We have to be really careful about that—that’s how you get pregnant! Once a year—maybe!”
Yuzu: “No . . . something more than kissing . . .”
Mei: “There is nothing more than kissing!”
Yuzu: [Holds up hand] “Something to do with . . . “ [Shakes head] “No, now it’s gone . . .”
Me: “Just forget it, and come give Kumagoro his good-night hug.”
