Looking for any novels or manga that has a moment where the guy MCs demonstrates his girl/wife power. For example great houseworking skills like cleaning or cooking(not just them being able to cook but able to cook like a housewife). Or moments when the MC is able to pick good clothes for a girl on a shopping date and has style. Or when a guy can knit or sew. Or like in an isekai where they invent cosmetics like in Parallel World Pharmacy. It can also be a moment when the guy amazingly actually can understand girls/women like Yu Ishigam from Kagura-sama: Love Is War or like Tadano Hitohito from Komi-san wa Komyushou Desu. I just fine it so cute and at the same time so smooth and cool. It just earns them points.
there is that Ore Monogotari (pardon any misspelling) unfortunate guy down on his luck whrn it comes to love finally saves a girl and she asks him out. i dont remember it entirely, but i think he had girl power moments. plus, it is one of the pinkest anime/manga that i actually enjoy.
Maybe someone like Takasu Ryuuji (Toradora!), Ichijou Raku (Nisekoi), Komiya Chihiro (Shounen Maid) and/or Kimihiro Watanuki (xxxHolic) Edit/add-on: Ijyuuin Akira (20 Mensou ni Onegai!! & CLAMP Gakuen Tanteidan), Master (Isekai Shokudou), Senshi (Dungeon Meshi) & Araiwa-san (Cooking Papa)
MC of "Tate no Yuusha no Nariagari" (aka., Naofumi), can cook, make jewellery, and can sew/mend normal clothes as well. Plus he later on takes on a bunch of kids and become sort of motherly figure to them.
