First, gotta appreaciate how the Artist manages to convey so much in each frame of the manga, seriously, this artist is so good that he could carry a dumpster fire alone with his art and attention to details.
Second we need a Milf in the harem asap, I know Guild Girl and Manager Girl are big, but Milfs in this manga are another tier completely. And the artist also draw dudes very well, the dudes on baths are ripped asf and even the MC despite being a office worker has some cool muscles.
Third I love how Theresa is covering the MC eyes when there's any pervert scene, it shows that her bond with the MC is making her regain some of her humanity back even in form of jealously. And she also is marking territory as the first and best wife, the best girl indeed.
Fourth I'm also loving the scenes with Gambler girl, she's becoming one of my favorites together with Theresa, I love how serious the other girls are in battle meanwhile she makes company to the MC and keeps fooling around, it reminds me of the Clowns of Dragon Quest 3 that would waste a turn or two doing useless things in battle, but had absurd luck which helped dropping seeds or items.
