Both involve MULTIPLE RELATIONSHIPS, psychology and comedy-darkness blend.
In KMHM there's 7 characters/7 relationships due to male leads multiple personality disorder; meanwhile in Love Shuffle there's several different relationships due to a group of people deciding to "shuffle"/swap relationship partners with each other multiple times, to test if there exists such a thing as "soulmate"/one person that's better for you.
While both have multiple relationships, both also have a couple of rootable MAIN couples/OTPs with a good romance arc; making shipping easier, while keeping the complexity of the relationship/s and story in tact!
Recommended for fans of psychology, drama-comedy combo, deep and complex characters and story and believable OTP/romance.
Both high quality dramas that deserve a better rating on MDL.
