Not really anything alike apart from the fact that body switch is possible, a good watch and not too long so if you have a short attention span/ want to binge watch then this is good for you <3
Similar theme of having two bodies for one soul. When the other slept the other awake. Both tackle the problem of appearance. But Debut focused more on dreams as a star. Lookism is more than that and a bit more complex.
You'll have some relief watching Debut. As it's about idol, they have some great OSTs too.
MCs leading a double life, and people treating them differently based on their looks. They make genuine friends in the process.
No body switching in Shadow Beauty like in Lookism though.
