It is kind of similar as both male leads have mysophobia and both have cleaning companies also. The female leads are kind of poor. This is the similarity I found
Same cute adorable socially clueless character as ML as well as actor in the role. Both have an illness that adds angsty dimensions. Both dramas have the FL and ML working together. FL is even a cleaner in both dramas at some point in time. Most importantly both dramas have a similar look and feel. Colour palettes and light romance sprinkled with bit is external trials.
both are based around a man with OCD who creates a product and company to help him with his illness. until he meets a woman who he is comfortable being around and who helps him deal with some of his issues which begins his road to recovery. also, His family doesn't believe he has OCD in the beginning but they slowly begin to understand him and his illness.
