Yo this is amazing but I literally just comment here to recommend ya all to read "The villainess wants to slim down her husband" because it is just FREAKING GOOD!!!
Also, in "The villainess wants to slim down her husband", the ML and FL actually falls in love with each other (abeit slowly) and god they're just so sweet and cute together i can't-
Also, the end/climax is good, it can be a bit predictable, but I think that's for you to read and decide.
TLDR: GO AND READ "The villainess wants to slim down her husband"!!!!
