Continued love is kinda like this. It has the same plot with personality change, and an already established married couple. I think it's a bit heavier tho, i don't remember cus it's been a while. But if you are looking for the same humor i don't think this is the same
any BL reccs like this? it doesn't have to be the same trope but at least the same vibes? i really like how hilarious this is (≧∀≦)
