He sucked Mako's breast finally! ☺
Fortunately the mistress intention is only to go to her era (future/past?).
Unfortunately the manga ends here, there's still need many things to be resolved, but I don't think there's any major threat beside her (and the ghost), I had good fap so far (eventhough I miss Mako's pubic hair, it's last seen on chapter 9)
That's the end??
It feels like there could have been more to this since they opened up the lore more with the time travel angle
but sigh, I can only hope there was a harem ending in this manga
