I just finished Sweat and Soap and I still have a hangover of how realistic it is and how nice the pacing is all the way to the ending. No 3rd party, no villain trying to destroy them. Both characters communicate openly and are very mature. Smut is moderate (not the focus)

So can you suggest something similar that is already complete and ending is not rushed with epilogue is nice also?
Some of those I have finished
Sesame salt and Pudding
Fruits Basket (more of a shoujo)

Bonnouji
Takane no Ran-san

Not completed but within the scope of category you’re looking for : Honnou Switch

wine baths?
