I Wanna Be Sup'Tar (2015)

hero character match and heroine looks like aom am. arrogant star, girl trying to get back into her house that is now owned by the star, sleeping outside in the rain, bargaining for the right to stay in the house...so it definitely like fullhouse

The main guy in both pretends to be gay so the main leads cohabits due to this reason

-Kasetsin Puttichai as once again the hot main role. Here he is more in the picture.
-The similiar thing here is the main role and that he once again is in the same industry.
They do not have the exact same story line but the story is about surviving in the industry -and it's about the female role getting help from a better male actor and develop emotions towards each other.
-How a little newbie female actor can get so close to such a big star among the actors higher up.

If you liked watching the love story of Peesang and Botklon, this is another cute love story of a fallen superstar and a girl who chases after her dream to become a superstar. While the ML helps the FL to fight for her dream, they both fall in love for each other.

These two dramas are similar because a superstar and a normal not so famous person live togethe. I don't know what else to write because this drama has just started BUT------- watch it. You'll understand how similar they are.

Plot-wise these two have pretty much nothing in common. If you enjoy the acting of the female lead on the other you will enjoy the acting in the other one too. I personally found the female leads pretty similar with their over-acting characters and tacky clothing. They're similar to the point I would think they're siblings.

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.

Both have the girl living with a famous celebrity who she thinks is gay, except in RNJJH her gay best friend and his twin secretly swap places.

Both have to do with romance with or between celebrities. Differences being that 'Nang Rai Sai Lab' is a little darker and contains a lot of action, compared to the light and fluffy 'Wannueng Jaa Pben Superstar.'

They're both very cute and romantic and the same actor stars in both dramas.
