If you are a fan of this cdrama, The Day Of Becoming You, a sweet romantic treat with lots of comedy and chemistry, then you would enjoy kdrama, Branding in Seongsu starring Kim Ji Eun and Lomon.
While not a body swap drama, the Main Leads share each other’s pain/emotions etc. From what I’ve seen, the funny scenes are quite similar and there are topics from the female/male perspective discussed like e.g. periods. The FL are also both strong and (at least in LU) the Main leads learn through each other.
