Yakumo-san wa Ezuke ga Shitai.

If you find the idea of surrogate parents interesting then you would probably enjoy Yakumo-san. Both feature a widower/widow cooking for a high school student. Pretty much a genderswapped cast, only without Tsumugi. Similar amounts of blushing are featured throughout.
Weirdly enough both also feature a upbeat blond female side character with multiple male siblings.
