Similar premise with roles reversed. I think Whos The One is more suitable for guys

Similar Japanese woman and Korean man love story. Marriage War is a special and very lighthearted

Love is not Blind is more thought provoking and also about exes. LINB makes you reflect on relationships and life in general and was a very successful film

Similar plot about family not related by blood. I found Ugly Alert more touching though.
