Both stories are similar in terms of the fantasy world. My roommate is a Gumiho is about a guy who is a gumiho, very likable, warm character. My love from the star is about a guy who is an alien.
Both dramas are light and don't have a lot of revenge. As well as the main girl disguise her identity that she is wealthy.
This has a very similar story line, except that in Wannueng Jaa Pben superstar the parents of the girl sold the house, but she stayed in Thailand to become a superstar.
