The scanlation stopped long ago, but you can read the entire Japanese raws for free. The author also released another age gap sequel -- 蜜会 (Mitsu-kai). It's about aunt-and-nephew relationship of Kaga-san's son and his late wife's sister who played important evil roles in this manga. It's heaven for age gap fans to see Kaga-san and Mikari fight for their love.

There's only 2 chapter out and after reading them, I won't stick around for a third. Did you guess that the old man hesitates moving in with a 19 year old? Did you guess that he sees her with a younger male coworker and realizes his age difference? Did you guess that the male coworker helping the female lead falls in love with her and makes a move on her?

This is just forcing the drama on brittle bones of a manga. It's just not good writing.
